 abstract ={Personalised electronic tourist guides (PETs) are mobile hand-held devices able to create tourist routes matching tourists' preferences. Transportation information has been identified as one of the most appreciated functionalities of a PET. We model the tourist planning problem, integrating public transportation, as the time-dependent team orienteering problem with time windows (TD-TOPTW) in order to allow PETs to create personalised tourist routes in real-time. We develop and compare two different approaches to solve the TD-TOPTW. Experimental results for the city of San Sebastian show that both approaches are able to obtain routes in real-time.},

 abstract ={Recent advances in browser technology along with the widespread proliferation of Graphics Processing Units (GPUs) have enabled new visualization capabilities in the browser. Analyzing the connectome requires intensive preprocessing along with realtime visualization for results exploration. The introduction of WebGL [1] has made exploration of such data possible in the browser, enabling visualizations across a range of devices without any client-side software requirements other than a WebGL-enabled browser. This poster introduces several visualization techniques that were developed for exploration of connectome data.},

 abstract ={Most ontologies are poorly documented, thus not being optimally accessible to potential users and ontology reuse services. A first step towards ontology documentation is the development of an explicit schema for the systematic and comprehensive description of ontologies. To provide an informed background for such a schema, we performed a survey of the most recent ontology engineering technology, and the types of information for describing ontologies. We introduce an ontology metadata schema, which as part of the OMV standard, was evaluated through professional reviews. A second step is the provision of automatic techniques to acquire such documentation. For this purpose we have developed the OMEGA (Ontology MEtadata GenerAtion) algorithm, which automatically generates metadata about arbitrary ontologies on the Web and is available as Web application and REST Web service. It was evaluated with very promising results, providing thus a core building block for the realization of fully-fledged ontology location services.},

 abstract ={This paper presents a new approach to make current and future television universally accessible. The proposed approach provides a means of universal accessibility both for remotely operating the TV set and for interacting with online services delivered through the TV. This proposal is based on the ISO/IEC 24752 “Universal Remote Console” (URC) standard. This standard defines an abstract user interface layer called the “user interface socket” and allows the development of pluggable (plug-in) user interfaces for any type of user and any control device. The proposed approach lays the foundation for the development of advanced user interfaces that can be interacted within various modalities. Different prototypes have been developed based on this approach and tested with end users. The user tests have shown this approach to be a viable option for the proposed scenarios. Based on the experience gathered with the prototypes, recommendations and implementation options are suggested for commercial adoption.},

 abstract ={Nowadays the retrieval of multimedia assets is mainly performed by text-based retrieval systems with
powerful and stable indexing mechanisms. Migration from those systems to content-aware multimedia retrieval systems is a common aim for companies from very diverse sectors. In this paper we present a semantic middleware designed to achieve a seamless integration with existing systems. This middleware outsources the semantic functionalities (e.g. knowledge extraction, semantic query expansion,…) that are not covered by traditional systems, thereby allowing the use of complementary content-based techniques. We include a list of key criteria to successfully deploy this middleware, which provides semantic support to many different steps of the retrieval process. Both the middleware and the design criteria are validated by two real complementary deployments in two very different industrial domains.},

 abstract ={We have detected the lack of a widely accepted knowledge representation model in the area of Blood Vessel analysis.

It will allow easy reuse of software pieces through appropriate abstractions, facilitating the development of innovative methods, procedures and applications. We include a thorough review of vascular morphology image analysis. After the identification of the key representation elements and operations, we propose a Vessel Knowledge Representation (VKR) model that would fill this gap. We give insights into its implementation based on standard Object-Oriented Programming tools and paradigms. The VKR would easily integrate with existing medical imaging and visualization software platforms, such as the Insight ToolKit (ITK) and Visualization Toolkit (VTK). },

 abstract ={Virtual engineering applications (VEA) are used through the whole product life cycle (PLC) process; their complexity and pervasiveness make them  an ideal scenario for development and testing of software engineering innovations. More precisely, VEAs have problems when they need to share their specific knowledge. They suffer semantic loss situations, and they hardly use any semantic tools. This work proposes a new approach to solving these kinds of problems based on semantic technologies, allowing the seamless sharing of information and knowledge between VEAs involved in a PLC scenario. This approach is validated through a plant layout design application, where several VEA can cooperate and share their knowledge, accomplishing the design task.},

 journal ={EURASIP Journal on Advances in Signal Processing},
 year ={2011},
 keys ={Image processing, object tracking, Monte Carlo methods, intelligent vehicles},
 month ={October},
 volume ={October 2011},
 abstract ={This paper presents a probabilistic method for vehicle detection and tracking through the analysis of monocular images obtained from a vehicle-mounted camera. The method is designed to address the main shortcomings of traditional particle filtering approaches for use in traffic environments. Namely, Bayesian methods based on importance sampling do not scale well as the dimensionality of the feature space grows, which involves important limitations when it comes to tracking of multiple objects. Alternatively, the proposed method is based on a Markov chain Monte Carlo (MCMC) approach, which allows efficient sampling of the feature space. The method involves important contributions as regards both the motion 2 Jon Arr´ospide et al. and the observation models of the tracker. Indeed, as opposed to particle filter-based tacking methods in the literature, which typically resort to observation models based on appearance or template matching, in this work a likelihood model that combines appearance analysis with information from motion parallax is introduced. Regarding the motion model, a new interaction treatment is defined based on Markov Random Fields (MRF) that allows to handle possible inter-dependencies in vehicle trajectories. As for vehicle detection, the method relies on a supervised classification stage using Support Vector Machines (SVM). The contribution in this field is two-fold. First, the mostly rectilinear structure of vehicles is capitalized on to define a new descriptor based on the analysis of gradient orientations in concentric rectangles. This descriptor involves a much smaller feature space compared to traditional descriptors, which are too costly for real-time applications. Second, a new vehicle image database is generated to train the SVM and made public. The proposed vehicle detection and tracking method is proven to outperform existing methods and to successfully cope with the challenging situations contained in the test sequences.},

 volume ={4, number 3},
 abstract ={Nowadays, tourism has become a very important industry in the international economy. Information and communication technologies are in constant development; they progress worldwide and across sectors. Their applications in tourism and tourist resources is rapidly increasing, reaching new, innovative and sometimes amazing results in terms of effectiveness, productivity, quality, and customer satisfaction. Exploring the interaction between technologies and tourism is difficult and challenging. Specifically, using virtual world technologies as a new means of information for potential tourists is a big challenge where the actual methods, goals and needs still need to be exactly identified. Within the Metaverse1 project, Innovalia Spain (in association with other European partners) has created a \'technologies laboratory\' for the tourism sector within a virtual world; this laboratory is called the Virtual Travel Use Case. A new island has been implemented in Second Life, as the playfield of the Virtual Travel Use Case. This island represents the hot spots of Gran Canaria (one of the seven islands making up the archipelago of Canary Islands, Spain). This is the starting point for analysing, testing and validating developments of tourism in virtual worlds, and the application part of the related research activity. The main technologies implemented in the Virtual Travel Use Case are listed below. They aim at making the tourists' experience in a virtual world even more interesting. UNIVERSITAT POMPEU FABRA has developed a platform for authoring and rendering Soundscapes (sound ambiances) in virtual worlds. INRIA Talaris has developed multilingual tools for tourists within virtual worlds, the MLIF: The Multi Lingual Information Framework for virtual worlds. UTRECHT UNIVERSITY has researched and developed the Path and Camara Planning tools in virtual worlds. In addition to these four technologies, we contributed to the MPEG-V Standard. In this respect, the work of VICOMTECH focused on defining the attributes that can identify each avatar as unique, and afterwards, a high-level XML-based specification of these attributes has been created. The specification has been called ADML (Avatar Definition Markup Language) and it has been included into the new MPEG-V standard for interoperability between virtual worlds. IMS has designed and implemented the Video streaming model within virtual worlds.
This paper aims at analyzing why and how virtual worlds can become an important platform for tourism-oriented areas to promote a destination in general, and their local heritage and tourist added-value services in particular. The document will also introduce the design of the first prototypes and the validation results of the four specific technologies tested at the Virtual Travel Use Case (Soundscape generation, Multilinguality, Video streaming and Path and Camera Planning). Finally, the contribution to the MPEG-V standard will also be detailed in the paper.},

 keys ={Computer vision, tracking, traffic image analysis, traffic information systems, 3-D reconstruction},
 month ={November},
 pages ={1-14},
 volume ={99},
 abstract ={In this paper, we present a robust vision-based system for vehicle tracking and classification devised for traffic flow surveillance. The system performs in real time, achieving good results, even in challenging situations, such as with moving casted shadows on sunny days, headlight reflections on the road, rainy days, and traffic jams, using only a single standard camera. We propose a robust adaptive multicue segmentation strategy that detects foreground pixels corresponding to moving and stopped vehicles, even with noisy images due to compression. First, the approach adaptively thresholds a combination of luminance and chromaticity disparity maps between the learned background and the current frame. It then adds extra features derived from gradient differences to improve the segmentation of dark vehicles with casted shadows and removes headlight reflections on the road. The segmentation is further used by a two-step tracking approach, which combines the simplicity of a linear 2-D Kalman filter and the complexity of a 3-D volume estimation using Markov chain Monte Carlo (MCMC) methods. Experimental results show that our method can count and classify vehicles in real time with a high level of performance under different environmental situations comparable with those of inductive loop detectors.},

 month ={April},
 pages ={149-163},
 volume ={14},
 abstract ={A new line segment detection approach is introduced in this paper for its application in real-time computer vision systems. It has been designed to work unsupervised without any prior knowledge of the imaged scene; hence, it does not require tuning of input parameters. Although many works have been presented on this topic, as far as we know, none of them achieves a trade-off between accuracy and speed as our strategy does. The reduction of the computational cost compared to other fast methods is based on a very efficient sampling strategy that sequentially proposes points on the image that likely belong to line segments. Then, a fast line growing algorithm is applied based on the Bresenham algorithm, which is combined with a modified version of the mean shift algorithm to provide accurate line segments while being robust against noise. The performance of this strategy is tested for a wide variety of images, comparing its results with popular state-of-the-art line segment detection methods. The results show that our proposal outperforms these works considering simultaneously accuracy in the results and processing speed. },

 abstract ={This paper introduces a new method for the simultaneous computation of sets of lines meeting at multiple vanishing points through the use of the Expectation–Maximisation (EM) algorithm. The proposed method is based on the formulation of novel error functions in the projective plane between lines and points which involve the use of non-linear optimisation procedures that allow to treat equally finite and infinite vanishing points. These functions are included into the EM framework, which handles the multi-modality of the problem naturally with mixture models. Results show that the proposed method of joint computation of vanishing points and lines converging at such points enhances the robustness and the accuracy of locating these points.},

 abstract ={This article introduces a 3D vehicle tracking system in a traffic surveillance environment devised for shadow tolling applications. It has been specially designed to operate in real time with high correct detection and classification rates. The system is capable of providing accurate and robust results in challenging road scenarios, with rain, traffic jams, casted shadows in sunny days at sunrise and sunset times, etc. A Bayesian inference method has been designed to generate estimates of multiple variable objects entering and exiting the scene. This framework allows easily mixing different nature information, gathering in a single step observation models, calibration, motion priors and interaction models. The inference of results is carried out with a novel optimization procedure that generates estimates of the maxima of the posterior distribution combining concepts from Gibbs and slice sampling. Experimental tests have shown excellent results for traffic-flow video surveillance applications that can be used to classify vehicles according to their length, width, and height. Therefore, this vision-based system can be seen as a good substitute to existing inductive loop detectors.},

 abstract ={Disabilities that follow cerebrovascular accidents and spinal cord injuries severely impair motor functions and thereby prevent the affected individuals from full and autonomous participation in activities of daily living. Rehabilitation therapy is needed in order to recover from those severe physical traumas. Where rehabilitation is not enough to restore completely human functions then functional compensation is required. In the last years the field of rehabilitation has been inspired by new available technologies. An example is given by rehabilitation robotics where machines are used to assist the patient in the execution of specific and physical task of the therapy. In both rehabilitation and functional compensation scenarios, the usability and cognitive aspects of human-machine interaction have yet to be solved efficiently by robotic-assisted solutions. Hybrid systems combining exoskeletal robots (ERs) with motor neuroprosthesis (MNPs) emerge as promising techniques that blends together technologies that could overcome the limitations of each individual one. Another promising technology which is rapidly becoming a
popular application for physical rehabilitation and motor control research is Virtual Reality (VR). In this chapter, we present our research focuses on the development of a new rehabilitation therapy based on an integrated ER-MNP hybrid systems combined with virtual reality and brain neuro-machine
interface (BNMI). This solution, based on improved cognitive and physical human-machine interaction, aims to overcome the major limitations regarding the current available robotic-based therapies.},

 abstract ={The goal of this chapter is to encourage an open discussion about current and future technological
support for knowledge sharing and learning. This support can be especially beneficial for communities of practice, where technology can bring increasingly geographically distant companies and knowledge closer together. The chapter introduces new technologies based on emergent Web3D and which can improve current ways of sharing knowledge and providing eLearning support. These are 3D virtual worlds as knowledge sharing tools and the concept of serious games as a way for improving learning processes. An application that combines both technologies would unite the main features of constructivist learning theories, and therefore, be a useful tool for supporting communities of practices’ learning and knowledge flow in a very dynamic way. This chapter also suggests what ideal tools for knowledge sharing and learning on Future Internet could be like, the advantages that their use could provide and the factors the authors believe should be improved to turn this ideal tool into a reality.},

 abstract ={Many organizations have developed Communities of Practice and they are one of the most important

With this in mind, this chapter focuses on the context factors that influence the development of Communities of Practice. To this end, we review different cases of Communities of Practice within various organizations. Our analysis provides: (a) a reflection on the Context factors in the process of integrating Communities of Practice, (b) an analysis of the impact of these factors on the development of Communities of Practice in different organizations and (c) the conclusions of the study. This study is based on the general idea that Communities of Practice are a valid management tool for organizations.

 abstract ={Fires disasters provoke great destruction of high valuable environments and economical losses, especially when they are located in urban areas. The usage of Virtual Reality Simulator to support the training process of fire fighters and managers has two main advantages: i) it supports the simulation of scenarios like big city fires that could not be simulated in the real world ii) it reduces the accident risks as users are trained to experience situations as ‗alike‘ as possible to real fire. The success of the Virtual Reality Simulator depends on how close to reality the simulation process is; it also requires the integration of heterogeneous data sources like maps and cadastre. Both these aspects are met in this paper by a careful management of Semantics in the information system. Semantics are useful firstly to have a better model of the fire fighting process and a better adaptation of the simulation environment to the user profile. They are useful secondly to facilitate the integration of data from heterogeneous sources. This work discusses and presents some preliminary results about how Semantic can enhance Virtual Reality Simulators in the fire fighting context.}

This hybrid network allow tourists to access tourist multimedia contents while on the destination, combining several telecommunication networks in order to provide innovative added-value services. This paper presents the design, implementation and evaluation in a small destination of a hybrid network composed of point-to-multipoint technologies for the provision of general information about the destination (Points of Interest, agenda, food and beverage, accommodation) that are the same for all tourists; and point-to-point technologies for a point-to-point interaction to access personalized added-value services (ticket purchasing,personalized contents).}

Many long-term aspects are still in an experimental stage, where the long-term impact on provisioning and usage is as yet unknown. While first attempts at this field focused on service provisioning for enterprises, cloud is reaching individuals nowadays. Our proposal is to go a step further and, based on the proven benefits of the Cloud, improve Internet and technology access for those people always left behind when any technological progress takes place. This paper presents the Cloud-based Assistive Technology Service delivering to individuals who face technology accessibility barriers due to ageing or disabilities. An example of how an Assistive Service is delivered to an individual in an easy and seamless way is given as a demonstration of how the future should be. This proof of concept has been developed within the INREDIS research project.}

Multidisciplinary, heterogeneous and disperse clinical information and decision criteria have to be handled by CDSSs. For such tasks, Knowledge Engineering (KE) techniques and semantic technologies are very suitable, as they support (i) the integration of heterogeneous knowledge, (ii) the expression of rich and well-defined models for knowledge aggregation, and (iii) the application of logic reasoning for the generation of new knowledge. In this paper we propose a generic architecture of a CDSS based on semantic technologies, which also considers the reutilization and enhancement of former CDSS in an organization. Particularly, an implementation of the proposed architecture is also presented, aiming to support the early diagnosis of AD.},

 abstract ={Alzheimer Disease (AD) has become a major issue in developed countries due to medical advances that have extended the population longevity. Recent advances in early detection date the initial stages of AD several years before the first recognizable symptoms appear visible. While at present time, there has not been recognized a single cause for AD, the common approach to support the diagnosis is based on diagnostic image processing, psychological tests, neurological tests, etc. This method produces a large amount of data that has to be taken into account by the physicians when they perform their diagnosis. In this paper we present a Knowledge Engineering diagnosissupport tool for the detection of AD where ontologies and semantic reasoning play a fundamental role. Our work is intended to aid physicians in the early detection of AD by using multidisciplinary knowledge gathered, and inference and reasoning over the underlying Knowledge Bases. A test example of our tool is also shown and discussed.},

An implementation of this approach has been carried out as a multimodal/multipurpose natural human computer interface for elderly people, by creating adapted graphical user interfaces and navigation menus together with multimodal interaction (simplified TV remote control and voice interaction). In
addition, this user interface can also be suited to other user groups. We have tested a prototype that adapts the videoconference and the information service with a group of 83 users. The results from the user tests show that the group found the prototype to be both satisfactory and efficient to

 abstract ={There are many scenarios where there is still a need to give a real alternative to the private vehicle, e.g., highly demanded services and infrastructures or big events that receive large influx of people that have to move at the same time to the same place. This paper describes the design and development of a new sustainable mobility solution, presenting an integrated real time management system that allows serving several users sharing a common origin or destination with similar schedules. Three different algorithms are tested in order to decide which one performs best to be included in the platform (linear programming, genetic and routing algorithms). The objective of the algorithms is to find the optimal set of routes, which is the one that uses the minimum number of vehicles to service all requests. Also, passengers are ensured that the travelling time increase due to other pick-ups will not exceed a certain percentage of the minimum time required to make the direct journey. Finally, it is concluded that the best approach stands on a combination of the presented algorithms.}

 abstract ={In this paper we propose a new method for the automatic detection and tracking of road traffic signs using an on-board single camera. This method aims to increase the reliability of the detections such that it can boost the performance of any traffic sign recognition scheme. The proposed approach exploits a combination of different features, such as color, appearance, and tracking information. This information is introduced into a recursive Bayesian decision framework, in which prior probabilities are dynamically adapted to tracking results. This decision scheme obtains a number of candidate regions in the image, according to their HS (Hue-Saturation). Finally, a Kalman filter with an adaptive noise tuning provides the required time and spatial coherence to the estimates. Results have shown that the proposed method achieves high detection rates in challenging scenarios, including illumination changes, rapid motion and significant perspective distortion. }

 abstract ={This article presents a methodology for reconstruction of 3D faces which is based on stereoscopic images of the scene using active and passive surface reconstruction. A sequence of Gray patterns is generated, which are projected onto the scene and their projection recorded by a pair of stereo cameras. The images are rectified to make coincident their epipolar planes and so to generate a stereo map of the scene. An algorithm for stereo matching is applied, whose result is a bijective mapping between subsets of the pixels of the images. A particular connected subset of the images (e.g. the face) is selected by a segmentation algorithm. The stereo mapping is applied to such a subset and enables the  triangulation of the two image readings therefore rendering the $(x,y,z)$ points of the face, which in turn allow the reconstruction of the triangular mesh of the  face. Since the surface might have holes, bilateral filters are applied to have the holes filled.
The algorithms are tested in real conditions and we evaluate their performance with virtual datasets. Our results show a good reconstruction of the faces and an improvement of the results of passive systems.},

rendering emphasis in the local client, our system takes advantage of its power, while at the same time eliminates processing from unreliable bottlenecks (e.g. network). The system developed articulates in efficient manner the capabilities of the recently released WebGL standard, which makes available the accelerated graphic pipeline (formerly unusable). The dependency on specially customized hardware is eliminated, and yet efficient rendering rates are achieved. The Web increasingly competes against desktop applications in many scenarios, but the graphical demands of some of the applications (e.g. interactive scientific visualization by volume rendering), have impeded their successful settlement in Web scenarios. Performance, scalability, accuracy, security are some of the many challenges that must be solved before visualWeb applications popularize. In this publication we discuss both performance and scalability of the volume rendering by WebGL ray-casting in two different but challenging application domains: medical imaging and radar meteorology.},

Taken into account the choices made by the visitor, the system infers a dynamic profile.

Each resource is associated with a weight which indicates the utility of that resource tot he profile of the visitor.

 abstract ={The main objective of Personalised Electronic Tourist Guides (PETs)is to help tourists in personalised route generation tasks, offering added-value functionalities. PETs provide an integrated solution for route generation based on the profile and constraints of tourists, and up-to-date Points Of Interest (POIs) and destination information.

The main objective of this thesis is the implementation of advanced algorithms to improve the personalised route generation functionality of PETs, including public transportation. This work proposes different approaches to solve new simplified versions of the Tourist Trip Design Problem (TTDP)in real-time. On the one hand, an efficient heuristic for the Multi Constrained Team Orienteering Problem with Time Windows (MCTOPTW), which adds multiple constraints to previous existing models, is proposed. Moreover, this heuristic is  tested  with related approaches from the literature and with a new test set we propose for the MCTOPTW.

On the other hand, two different solution approaches to tackle the time-dependent travel times for the Time Dependent Team Orienteering Problem with Time Windows (TDTOPTW), an extension of previous models including public transportation, are presented. All of the approaches are tested with a test set based on the city of San Sebastian.

Finally, a prototype developed to test the viability of the TDTOPTW solution algorithms in a real world tourist environment is described. 
Moreover, the results of the validation performed with the Local Tourist Office (LTO) staff and tourists visiting the city are shown.}

Often this condition forces the user to select a particular API, conditioning the future development and maintenance of the created application. This project presents a solution as a generic API or meta API, which provides an architecture that detaches the computational representation of the graph from a particular implementation.

In order to get a realistic illusion, the real and virtual objects must be properly aligned with respect to each other, which requires a robust real-time tracking strategy - one of the bottlenecks of AR applications. In this paper we describe the limitations and advantages of different optical tracking technologies, and we present our customized implementation of both recursive tracking and tracking by detection approaches. The second approach requires the implementation of a classifier and we propose the use of a Random Forest classifier.
We evaluated both approaches in the context of an AR application for design review. Some conclusions regarding the performance of each approach are given.},

 abstract ={In this paper we present a low-cost system based on computer vision algorithms, which automatically inspects blow-molded plastic tubes used as outer covers of car dampers. The small size of the typical defects, the dark color and the specular reflection of this kind of black plastic parts makes the automation of this process a challenging task. Customers are becoming more exigent and they can even reject full batches of thousands of pieces only because of some non-valid samples (e.g., a limit of 10 defective tubes per million), therefore a correct quality checking is very important for companies. There are several standard industrial solutions designed for the automatic inspection of several kinds of pieces but not for these specific tubes. The proposed computer vision method obtains the tube surface aspect from the deformed laser beam projections observed by an uncalibrated camera, and identifies defects by comparing its shape with respect to the one expected. Experimental results show the suitability of the system to detect holes, burrs and deformations of these tubes, improving the quality checking process at a low cost.

 abstract ={Our research focuses on enabling users to interact with 3D graphics and interactive applications with the same content, appearance and interaction paradigm, on different platforms (Internet, Television, and Mobile Devices). The main contribution of this paper is the design and implementation of a platform-independent architecture for 3D graphics and content, validated in the entertainment and tourism sectors. In the case of entertainment, people enjoy communicating with others through virtual characters, also called avatars, e.g. in chat rooms. 3D avatars are being used increasingly and are gaining interest because they are often more visually appealing. As people can choose among different communications platforms, they should also be able to use a virtual character on these platforms to interact with other people at any time and in any place. The interaction of tourists with 3D graphics occurs in two stages of a trip and on two main platforms: the PC when planning their trip on the Internet, and a mobile device while at their destination. Tourist offices invest substantially in virtually recreating some of their most prominent tourism resources, therefore these models should be reusable on several platforms. The general architecture presented in this paper has been validated in several projects that are presented as case studies.},

It also discusses some open issues that, from the author’s point of view, should be taken into account when new virtual worlds, or new applications running over existing virtual worlds, are designed. The chapter provides a general definition of a virtual world, presents a historic review of these systems and describes the main features and elements that they are composed of. The chapter aims to be useful to the non-technical readers in that it shall provide a clearer concept of virtual worlds. In the case of technical readers, it attempts to be a reference for further research.},

 abstract ={Pluggable user interfaces is a software concept that facilitates adaptation and substitution of user interfaces and their components due to separation of the user interface from backend devices and services. Technically, the concept derives from abstract user interfaces, mainly in the context of device and service control. Abstract user interfaces have been claimed to support benefits such as ease of implementation, support for user-centered design, seamless user interfaces, and ease of use. This paper reports on experiences in employing pluggable user interfaces in the European project i2home, based on the Universal Remote Console framework, and the Universal Control Hub architecture. In summary, our anecdotic evidence supports the claims on the benefits, but also identifies significant costs. The experience reports also include some hints as to how to mitigate the costs.},

 abstract ={When tourists are at a destination, they typically search for information in the Local Tourist Organizations. There, the staff determines the profile of the tourists and their restrictions. Combining this information with their up-to-date knowledge about the local attractions and public transportation, they suggest a personalized route for the tourist agenda. Finally, they fine tune up this route to better fit tourists’ needs. We present an intelligent routing system to fulfil the same task. We divide this process in three steps: recommendation, route generation and route customization. We focus on the last two steps and analyze them. We model the tourist planning problem, integrating public transportation, as the Time Dependent Team Orienteering Problem with Time Windows (TDTOPTW) and we present an heuristic able to solve it on real-time. Finally, we show the prototype which generates and customizes routes in real-time.},

Visiting a location allows to collect its score as a reward. Traveling time between locations varies depending on the leave time. The objective is to obtain a route that maximizes the obtained score within a limited amount of time. In this paper we target the use of public transportation in a city, where users may move on foot or by public transportation. The approach can also be applied to the logistic sector, for example to the multimodal freight transportation. We apply an hybrid approach to tackle the problem. Experimental results for the city of San Sebastian show we are able to obtain valid routes in real-time.},

The proposed algorithm corrects some topological problems that may appear in the discretization process using the original grid.},

In addition, it has also become a priority need for many Spanish TV broadcasters, who will have to broadcast up to 90% of subtitled content by 2013 to comply with recently approved national audiovisual policies. APyCA, the prototype system described in this paper, has been developed in an attempt to automate the process of subtitling television content in Spanish through the application of state-of the-art speech and language technologies. Voice activity detection, automatic speech recognition and alignment, discourse segment detection and speaker diarization have proved to be useful to generate time-coded colour-assigned draft transcriptions for post-editing. The productive benefit of the followed approach heavily depends on the performance of the speech recognition module, which achieves reasonable results on clean read speech but degrades as this becomes more noisy and/or spontaneous.},

We build upon a fast mathematical method for on-demand sphere refitting during the animation and improve it for being applicable to any object, without dependency on its geometrical level of detail or its dynamic/static behavior. It uses sphere-plane intersection test as the exact test in the collision detection algorithm instead of the usual triangle-triangle one. Corner-trees, a special hierarchy that ensures the utilization of the plane-sphere intersection test is right, are also presented. In the worst case, the optimization decreases in 25% the time needed to process a frame in extreme conditions. The algorithm has been successfully tested on a real time and collaborative 3D virtual world.},

 abstract ={Ontology reuse is still an unsolved matter on the Semantic Web. Even though ontology specification languages provide a means for knowledge reuse and ontology management technology has evolved, ontology reuse is seldom encountered in applications. The more resources there are available, the more possibilities there are for ontology reuse, and paradoxically the more difficult it is to perform ontology reuse. This thesis proposes the notion of Ontological Resource Reuse Patterns (ORRPs), which state pattern-based knowledge about ontological resources to encourage ontological knowledge comprehension and to enhance ontology selection. ORRPs provide useful knowledge to improve ontology reuse to some extent.}

They need accurate information about accommodation, restaurants and tourist attractions, amongst others, in order to make the most of their experience. Mobile Augmented Reality (AR) can help tourists in the process of obtaining such information in a very simple way. MobiAR is an Android service platform for tourist information based on AR, which allows users to browse information and multimedia content about a city through their own mobile devices. Not only does the platform handle location-based information and user preferences, but it also takes advantage of computer vision technologies, so as to determine the tourist resource the user is interested in. This paper presents the main use cases covered by MobiAR and describes the main technological components. Furthermore, the validation scenarios that have been defined for San Sebastian and Valencia are also explained.}

It has been named after the 3-year strategic research project on language, speech and visual technologies for Basque carried out by several organizations, and built as a demonstrator of the technologies developed. Because the six modules comprising AnHitz have been implemented by different organizations using different operating systems, programming languages or libraries, it was impossible to build the demonstrator in a single executable or machine. As a result, the prototype has been constructed using separate programs in various machines that interact using network communication and web services protocols. Despite the employed approach having some drawbacks –mainly higher time delays when audio rendering is done via the web–, the outcome is indeed satisfactory, as it has allowed us to build a fully functional demonstrator that has showed good performance and acceptance in an evaluation made with 50 users, and has made a great impact on the Basque media.}

However, the technology has started to mature and move to industrical applications. Still, there are many things to do.

The diverse VEA are not necessarily available when information sharing is needed, a fact that represents a semantic loss as the knowledge gained by using one VEA can be lost if a data translation occurs (e.g. a Finite Element program is normally able to export only the geometry). In this paper we present an architecture and a system implementation based on semantic technologies which allows a seamless information and knowledge sharing between VEA in a PLC scenario. Our  approach is validated through a Plant Layout Design application which is able to collect knowledge provided by different VEA available. This work presents our system leaving a statistical analysis for future work, as at the moment our system is being tested.

The user can interact with the 3D virtual world using a Nintendo Wiimote for navigating through it and a Nintendo Wii Nunchuk for giving commands by means of hand gestures. We also present a dynamic gesture recognition procedure that measures the temporal advance of the performed gesture postures. Experimental results show how dynamic gestures are effectively recognized so that a more natural interaction and immersive navigation in the virtual world is achieved.},

 abstract ={An Abdominal Aortic Aneurysm is an abnormal widening of the aortic vessel at abdominal level, and is usually diagnosed on the basis of radiological images. One of the techniques for Abdominal Aortic Aneurysm repair is Endovascular Repair. The long-term outcome of this surgery is usually difficult to predict in the absence of clearly visible signs, such as leaks, in the images. In this paper, we present a hybrid system that combines data extracted from radiological images and data extracted from the Electronic Patient Record in order to assess the evolution of the aneurysm after the intervention. The results show that the system proposed by this approach yields valuable qualitative and quantitative information for follow-up of Abdominal Aortic Aneurysm patients after Endovascular Repair.

 abstract ={A surgical technique currently used in the treatment of Abdominal 	Aortic Aneurysms (AAA) is the Endovascular Aneurysm Repair (EVAR). This minimally invasive procedure involves inserting a prosthesis in the aortic vessel that excludes the aneurysm from the bloodstream. The stent, once in place acts as a false lumen for the blood current to travel down, and not into the surrounding aneurysm sac. This procedure, therefore, immediately takes the pressure off the aneurysm, which thromboses itself after some time. Nevertheless, in a long term perspective, different complications such as prosthesis displacement or bloodstream leaks into or from the aneurysmatic bulge (endoleaks) could appear causing a pressure elevation and, as a result, increasing the danger of rupture. The purpose of this work is to explore the application of image registration techniques to the visual detection of changes in the thrombus in order to assess the evolution of the aneurysm. Prior to registration, both the lumen and the thrombus are segmented.},

 abstract ={This paper presents a gesture recognition method for detecting and classifying both cyclic and non-cyclic human motion patterns in real-time applications. The semantic segmentation of a constantly captured human motion data stream is a key research topic, especially if both cyclic and non-cyclic gestures are considered during the humancomputer interaction. The system measures the temporal coherence of the movements being captured according to its knowledge database, and once it has a sufficient level of certainty on its observation semantics the motion pattern is labeled automatically. In this way, our recognition method is also capable of handling time-varying dynamic gestures. The effectiveness of the proposed method is demonstrated via recognition experiments with a triple-axis accelerometer and a 3D tracker used by various performers.

 abstract ={Object tracking in video-surveillance applications is a major topic in the signal processing and computer vision community. Its aim is to estimate properties of the imaged objects within a scene, such as their dimensions, motion, visual features, etc. Typically, object tracking is treated as an inference problem through probabilistic methods (Bayesian filtering), where the images act as noisy observations of the reality. The nature of inference methods allows abstracting from the specific problem or scenario and modeling very different situations under the same framework. In this field, particle filters (or non-linear, non-Gaussian filters) have emerged as a popular tool to make estimates of posterior distributions within the Bayesian frame. In this work, we review the use of particle filters and exemplify its performance with two typical vision problems: human tracking, and vehicle tracking.}

the analysis of the embryonic heart is still mostly done manually. This is a very laborious and expensive
task as each embryo has to be inspected visually by a biologist. We therefore propose to automatically
segment the embryonic heart from high-speed fluorescence microscopy image sequences, allowing
morphological and functional quantitative features of cardiac activity to be extracted. Several methods are
presented and compared within a large range of images, varying in quality, acquisition parameters, and
embryos position. Although manual control and visual assessment would still be necessary, the best of our
methods has the potential to drastically reduce biologist workload by automating manual segmentation}

 abstract ={This paper presents Q-WordNet, a lexical resource consisting of WordNet senses automatically annotated by positive and negative polarity. Polarity classification amounts to decide whether a text (sense, sentence, etc.) may be associated to \textit{positive} or \textit{negative} connotations. Polarity classification is becoming important for applications such as Opinion Mining and Sentiment Analysis, which facilitates the extraction and analysis of opinions about commercial products, on companies reputation management, brand monitoring, or to track attitudes by mining online forums, blogs, etc. Inspired by work on classification of word senses by polarity (e.g., SentiWordNet), and taking WordNet as a starting point, we build Q-WordNet. Instead of applying external tools such as supervised classifiers to annotate WordNet synsets by polarity, we try to effectively maximize the linguistic information contained in WordNet, thereby taking advantage of the human effort undertaken by lexicographers and annotators. The resulting resource, Q-WordNet, is a subset of WordNet senses classified as positive and negative. In this approach, \emph{neutral polarity} is seen as the absence of positive or negative polarity. The evaluation of Q-WordNet shows an improvement with respect to previous similar resources. We believe that Q-WordNet can be used as a starting point for data-driven approaches in Sentiment Analysis.

 abstract ={Nowadays it is widely recognized the need of developing a new generation of professional equipment for broadcasting that allows a considerable reduction of productions costs in dierent scenarios. We consider mobile multimedia scenarios where the incorporation of last generation hardware and the development of new software should allow: 1) to decrease the needs of human resources to produce (create, edit, and
distribute) audiovisual content; and 2) to increase the richness of the broadcasted product. In this paper, we propose a software system that helps technical directors to deal with many motorized videocameras attached to moving or static objects in wireless environments. We use mobile agents to carry out the processing tasks wherever they are needed. Thus, agents are in charge of tracking the location of interesting static or moving objects and the (current and possible) focus range of all the cameras, as well as of refreshing the query answers efficiently and continuously. We present a traditional rowing race in the Basque Country as motivating scenario, where technical directors may indicate interesting objects or geographic areas in run-time and the system is in charge of selecting the best shots from the cameras in the scenario.},

The focus of Virtual Engineering is to engage the human capacity for evaluation of complex systems and situations [2]. In this article, we present an architecture for the Semantic enhancement of Virtual Engineering Applications (VEA) through their embedded Virtual Engineering Tools. Our architecture follows a User- Intention-Domain schema and makes use of state of the art technologies like theSet of Experience Knowledge Structure and the Reflexive Ontologies in order to offer a better User experience with VEA. The main advantages of using Semantics in VEA can be summarized are: (i) an improved information and embedded Knowledge management, (ii) Enhancements in the search, knowledge and information sharing processes during the use of the VEA, (iii) The use of the intrinsic Knowledge embedded in the elements being described by the VEA and (iv) the empowerment of the User's knowledge and embedding of such knowledge in a structured and explicit conceptualization.},

 abstract ={Communities of practice (CoPs) have been taken into account by both practitioners and academics during the last ten years. From a strategic point of view, CoPs have shown their importance for the management of organizational knowledge by offering repositories of knowledge, improved capacity of making knowledge actionable and operational (Brown & Duguid, 1998) and by facilitating main maintenance, reproduction, and extension of knowledge (Brown & Durguid, 2001) . CoPs are also reported to achieve value creation and competitive advantages (Davenport and Prusak, 1998), learning at work (Swan et alt., 2002) that promotes organizational competitiveness (Furlong and Johnson, 2003), innovation, even a radical type (Swan et alt., 2002), responsiveness, improved staff skills and reduced duplication (du Plessis, 2008). This impressive list of achievements is not for free; some authors have pointed out the limits of CoPs (Duguid, 2005; Roberts, 2006; Amin & Roberts, 2008) from diverse points of view, including diversity of working environments, size, spatial or relational proximity, but mainly emphasizing the specificity of CoPs as a social practice paradigm, as it was defined by Wenger (1999, 2000) credited as the “inventor” of the “CoP” (Lave and Wenger, 1991). This chapter focuses on the consideration of CoPs as an organizational reality than can be managed (Thompson, 2005), the contradictions that the idea of managing them generates, and how these controversial points can be overcome in a sound and honest way. To do so, we review different cases of CoP’s within organizations intended for the managerial team to achieve important organizational goals. Our analysis provides: (a) a reflection regarding the Key Success Factors in the process of integrating communities of practice, (b) insight to the structure of a model of cultivation, intended as a guideline for new experiences in this area, and (c) an informative account of this model’s adaptation to the studied organizations.},

 abstract ={In this paper a videoconference system which has been specifically designed for persons with Alzheimer’s disease is proposed. The system has been designed to be used at home and it aims to improve communication between our target users and their caregivers. To maximize user-friendliness, the videoconference system is integrated into a common television set and, a realistic virtual character (i.e. avatar) that plays the role of a personal videoconference assistant is integrated on the TV set as well. To test the whole concept, a Wizard-of-Oz prototype has been built and then validated with a target group of 8 persons with Alzheimer’s disease. Validations took place at IZA, a day-care centre situated in San Sebastián (Spain) and were conducted by a group of validation and gerontological experts. The results showed that all sample subjects understood the instructions given by the avatar and were able to hold the videoconference satisfactorily.},

 abstract ={Recently, there has been an increasing interest to propose computational approaches based on image processing to automate the comparison of spatial gene expression patterns contained in transgenic embryo images. The first step is typically to classify the images between lateral and dorsal/ventral views, and then to align them along the anterior and posterior ends. While some methodologies have been recently proposed for standardizing images in Drosophila database, the case of zebrafish embryos have never been tackled. In this paper, we propose a standardisation methodology for building a zebrafish embryos image database. Details of our approach and the results of using this approach on a pilot dataset are presented. A quality test first allows
rejecting images presenting artefacts and which cannot be processed. The retained images are then classified, achieving a success rate of 93%.},

 abstract ={This paper presents a new architecture to make TV sets accessible for all. Our proposal is based on the ISO/IEC 24752 Universal Remote Console Framework standard. This standard defines an abstract user interface layer called the 'user interface socket' and allows the development of pluggable user interfaces for any type of user. Since this architecture is standards based, the development of compatible pluggable interfaces is open to any third party. Besides, a prototype of the proposed architecture has been built. In this prototype, the Universal Control Hub (UCH) has been used as the URC framework implementation, a PC with Windows Vista Media Center has been used as a TV Set-top box, and two pluggable UIs have been developed. These UIs consist of an accessible DHTML page for the visually impaired, and a multimodal client, which allows interaction via touch screen and speech. Finally, these two pluggable UIs have been validated with user groups with special needs and preliminary results show encouraging results.},

 abstract ={El uso de las prótesis endovasculares (EVAR) en el tratamiento de los Aneurismas de Aorta Abdominal (AAA) se ha mostrado como una técnica efectiva en la reducción de la presión del saco aneurismático y, en consecuencia, del riesgo de ruptura del mismo. Además, supone un procedimiento mínimamente invasivo en comparación con las técnicas tradicionales. Sin embargo, a largo plazo, la aparición de fugas (endoleaks) de origen diverso puede provocar una elevación de la presión en el saco (endotensión), con el consiguiente aumento del riesgo de ruptura. Para la detección y catalogación de las mismas, la Tomografía Computerizada (TC) se presenta como el método usual en el análisis y seguimiento de los pacientes. No obstante, en ocasiones, la localización de las mencionadas fugas por simple inspección visual puede resultar un proceso complejo, incluso, para personal médico experimentado.
El propósito del presente trabajo consiste en analizar la evolución de textura en aneurismas tratados mediante reparación endovascular, con el fin de comprobar si existe alguna relación entre variaciones en la textura y la aparición de fugas que ayude en la detección y catalogación de las mismas.},

Several resources, tools and applications have been developed in AnHitz, but we have also integrated many of these into a prototype of a 3D virtual expert on science and technology. It includes Question Answering and Cross Lingual Information Retrieval systems in those areas. The interaction with the system is carried out in Basque (the results of the CLIR module that are not in Basque are translated through Machine Translation) and is speech-based (using Speech Synthesis and Automatic Speech Recognition). The prototype has received ample media coverage and has been greatly welcomed by Basque society. The system has been evaluated by 50 users who have completed a total of 300 tests, showing good performance and acceptance.

After each iteration, the difference between the implicit and the explicit representations are reduced, and when the algorithm finishes, the implicit surface representation using the modified cubical grid is more detailed, as the results shall confirm. The proposed algorithm corrects some topological problems that may appear in the discretization process using the original grid.},

At present computed tomographic angiography (CTA) is the most commonly used examination for imaging surveillance for stent graft monitoring. However, endoleak complications can not always be detected by visual inspection on CTA scans. The purpose of this work was to study the application of image registration techniques to the detection of changes in the stent graft. Previously we segment the lumen using semi-automatic methods.},

 abstract ={In this paper we present computer vision strategies to detect automatically defects on blow-molded plastic tubes used as outer covers of car dampers. A correct quality checking of these tubes is very important as the customers of these pieces are becoming more exigent and, in certain occasions, they reject full sets of thousands of pieces because of some non-valid samples (e.g., a limit of 6 defective tubes per million). The automation of this process is challenging due to the small size of the expected typical defects, the dark color of the molded material and the specular reflection they have. Current standard industrial solutions for this kind of process are not capable of fulfilling the objective. The proposed system uses a laser beam and a single uncalibrated standard camera to scan the tube surface even without the need of any ambient illumination at all. The presented computer vision algorithms reconstruct the tube surface from the observed laser beam deformations and identify the defects by comparing the shape respect to the one expected.   Experimental results show the suitability of the proposed methods to detect holes, burrs and deformations on this type of tubes in real time, improving the productivity of the tube quality checking process.},

This requires the multimedia content to be annotated in order to create metadata which contains a concise and compact description of the features of the content. Metadata descriptions may vary considerably in terms of comprehensiveness or granularity depending on the tools used. In this paper, we present a new metadata description annotation tool for handling tourist multimedia content based on existing standards. In order to illustrate the performance of the ZERBITUR annotation tool, we designed a prototype and tested it on a relatively small database.

Additionally, due to the nature of the overall scheme, other valuable outcomes, such as pay per use insurance services or real time traffic management systems, will be obtained.}

 abstract ={The zebrafish embryo is a common model organism for cardiac development and genetics. However, the current method of analyzing the embryo heart images is still mainly the manual and visual inspection through the microscope by scoring embryos visually a very laborious and expensive task for the biologist. We propose to automatically segment the embryo cardiac chambers from fluorescent microscopic video sequences, allowing morphological and functional quantitative features of cardiac activity to be extracted. Several methods are presented and compared within a large range of images, varying in quality, acquisition parameters, and embryos position. Despite such variability in the images, the best method reaches a 70% of accuracy, allowing reducing biologists workload by automating some of the tedious manual segmentation tasks.},

For example, in biomedical imaging, it might be necessary to visualize 3D datasets obtained from CT or MRI scanners as a meaningful 2D image, in a process called volume rendering. As a result of the popularity and usefulness of volume data, a broad class of volume rendering techniques has emerged. Ray casting is one of these techniques. It allows for high quality volume rendering, but is a computationally expensive technique which, with current technology, lacks interactivity when visualizing large datasets, if processed on the CPU. The advent of efficient GPUs, available on almost every modern workstations, combined with their high degree of programmability opens up a wide field of new applications for the graphics cards. Ray casting is among these applications, exhibiting an intrinsic parallelism, in the form of completely independent light rays, which allows to take advantage of the massively parallel architecture of the GPU.

 year ={2009},
 address ={University of Minho, Braga, Portugal},
 month ={October},
 abstract ={Biomedical simulation makes use of 3D models as a virtual representation of the anatomy. Although current computer-based training and education systems have used such models, most of them fail to reproduce authentic anatomy, in terms of morphology, texturing and functional behaviour. The production of 3D organic models with a level of realism able to deceive medical professionals is still a challenge. In this paper, we propose to reach the highest level of organic realism allowed by current hardware and software graphics performance. Real-time or interactive rendering is out-of-scope. All the production will be made off-line, with special emphasis on anatomy correctness, realistic illumination and texturing. We propose a generic pipeline to accurately render human anatomy, mainly focusing on hard tissues. A case study is demonstrated in Odontology. }

Les images médicales ayant montré leur importance dans le suivi postopératoire des interventions des anévrismes, les études des images tomographiques devraient former les principales données de cette base de données.

 volume ={39},
 abstract ={In this article we introduce the necessary elements needed to integrate a decisional technology that offers a level of trust that enables them to be used for the implementation of decisional trust systems. Thus, we refer to this approach as decisional trust, which can be achieved through the use of elements such as decisional DNA, reflexive ontologies, and security technologies. Decisional trust operates on three fronts: (1) the construction of decisional DNA as a knowledge structure capable of collecting an organization's decisional fingerprints; (2) the construction of Reflexive Ontologies as descriptions of concepts and relations with a set of selfcontained queries in a domain of study; and (3) the addition of security technologies. Our approach extends the use of Decisional DNA and Reflexive Ontologies with the aim of offering trustable decisions, and introduces elements for the exploitation of embedded, trustable, decisional knowledge which, added to security elements, can lead to trustable technologies. Fully developed, it would advance the notion of administering trustable knowledge in the current decision making environment}

More specifically, key theoretical notions will be examined linked to the day-to-day events occurred in ARC. This IT-based organization traced an original expansion trajectory based on the creation of two spin-offs during its infancy period. This chapter highlights general concerns associated with knowledge management and the capacity of innovation which emerged during the business expansion process. For purposes of this study, these concerns can be classified in three main theoretical areas: Entrepreneurship, Interpreneurship and Intrapreneurship.},

One of the bottlenecks of such application is a robust real-time optical markerless tracking strategy. In this paper we focus on the development of tracking by detection for plane homography estimation. Feature or keypoint matching is a critical task in such approach. We propose to apply machine learning techniques to solve this problem. We present an evaluation of an optical tracking implementation based on Random Forest classifier.
