This volume constitutes the refereed proceedings of the 4th Iberian Conference on Pattern Recognition and Image Analysis, IbPRIA 2009, held in Povoa de Varzim, Portugal in June 2009.

The 33 revised full papers and 29 revised poster papers presented together with 3 invited talks were carefully reviewed and selected from 106 submissions. The papers are organized in topical sections on computer vision, image analysis and processing, as well as pattern recognition.

The security issues set by the global digitization of our society have had, and will continue to have, a crucial impact at all levels of our social organization, including, just to mention a few, privacy, economics, environmental policies, national sovereignty, medical environments. The importance of the collaborations in the various ?elds of computer s- ence to solve these problems linked with other sciences and techniques is clearly recognized. Moreover, the collaborative work to bridge the formal theory and practical applications becomes increasingly important and useful. In this context, and since France and Japan have strong academic and ind- trial backgrounds in the theory and practice of the scienti?c challenges set by this digitized world, in 2005 we started a formal French-Japanese collaboration and workshop series on computer security. The three ?rst editions of these French-Japanese Computer Security wo- shops in Tokyo, September 5-7, 2005 and December 4-5, 2006 and in Nancy, March 13-14, 2008 were very fruitful and were accompanied by several imp- tant research exchanges between France and Japan. Because of this success, we launched a call for papers dedicated to computer security from it's foundation to practice, with the goal of gathering together ?nal versions of the rich set of papers and ideas presented at the workshops, yet opening the call to everyone interested in contributing in this context. This v- ume presents the selection of papers arising from this call and this international collaboration.

This volume contains the papers presented at the 7th IAPR-TC-15 Workshop onGraph-BasedRepresentationsinPatternRecognition- GbR2009.Thewo- shop was held in Venice, Italy between May 26-28, 2009. The previous wo- shops in the series were held in Lyon, France (1997), Haindorf, Austria (1999), Ischia, Italy (2001), York, UK (2003), Poitiers, France (2005), and Alicante, Spain (2007). The Technical Committee (TC15, http: //www.greyc.ensicaen.fr/iapr-tc15/) of the IAPR (International Association for Pattern Recognition) was founded in order to federate and to encourage research work at the intersection of pattern recognition and graph theory. Among its activities, the TC15 encourages the organization of special graph sessions in many computer vision conferences and organizes the biennial GbR Workshop. The scienti?c focus of these workshops coversresearchin pattern recognition and image analysis within the graph theory framework. This workshop series traditionally provide a forum for presenting and discussing research results and applications in the intersection of pattern recognition, image analysis and graph theory

Motion analysis is central to both human and machine vision. It involves the interpretation of image data over time and is crucial for a range of motion tasks suchasobstacledetection,depthestimation,videoanalysis,sceneinterpretation, videocompressionandotherapplications. Motionanalysisis unsolvedbecauseit requires modeling of the complicated relationships between the observed image data and the motion of objects and motion patterns (e. g. , falling rain) in the visual scene. The Dagstuhl Seminar 08291 on Statistical and Geometrical Approaches to Visual Motion Analysis was held during July 13-18, 2008 at the International Conference and Research Center (IBFI), Schloss Dagstuhl, near Wadern in G- many. The workshop focused on critical aspects of motion analysis, including motion segmentation, the modeling of motion patterns and the di?erent te- niques used. These techniques include variationalapproaches,level set methods, probabilistic models, graph cut approaches, factorization techniques, and neural networks. All these techniques can be subsumed within statistical and geomet- cal frameworks. We further involved experts in the study of human and primate vision. Primatevisualsystemsareextremely sophisticatedat processingmotion, thus there is much to be learnt from studying them. In particular, we discussed how to relate the computational models of primate visual systems to those - veloped for machine vision. In total, 15 papers were accepted for these proceedings after the workshop. We werecarefulto ensurea high standardof qualityfor the accepted papers. All submissions were double-blind reviewed by at least two experts.

GeometricModelingandProcessing(GMP)isabiennialinternationalconference on geometric modeling, simulation and computing, which provides researchers and practitioners with a forum for exchanging new ideas, discussing new app- cations, and presenting new solutions. Previous GMP conferences were held in Pittsburgh (2006), Beijing (2004), Tokyo (2002), and Hong Kong (2000). This, the 5th GMP conference, was held in Hangzhou, one of the most beautiful cities in China. GMP 2008 received 113 paper submissions, covering a wide spectrum of - ometric modeling and processing, such as curves and surfaces, digital geometry processing, geometric feature modeling and recognition, geometric constraint solving, geometric optimization, multiresolution modeling, and applications in computer vision, image processing, scienti?c visualization, robotics and reverse engineering. Each paper was reviewed by at least three members of the program committee andexternalreviewers.Basedonthe recommendations ofthe revi- ers, 34 regular papers were selected for oral presentation, and 17 short papers were selected for poster presentation. All selected papers are included in these proceedings. We thank all authors, external reviewers and program committee members for their great e?ort and contributions, which made this conference a success.

This book constitutes the refereed proceedings of the 7th International Conference On Smart Homes and and Health Telematics, ICOST 2009, held in Tours, France, in July 2009.

ICIAR 2009, the International Conference on Image Analysis and Recognition, held in Halifax, Canada July 6-8, 2009, was the sixth in the ICIAR series of - nual conferences alternating between Europe and North America. ICIAR 2004 was held in Porto, Portugal, ICIAR 2005 in Toronto, Canada, ICIAR 2006 in P ovoa do Varzim, Portugal, ICIAR 2007 in Montreal, Canada, and ICIAR 2008 in Pov oa do Varzim, Portugal. The idea of o?ering these conferences came as a result of discussion between researchers in Portugal and Canada to enco- age collaboration and exchange, mainly between these two countries, but also with the open participationof other countries, addressing recent advances in the theory, methodology and applications of image analysis and recognition. For ICIAR 2009, wereceiveda total of 164full papersfrom 34 countries. The review process was carried out by the Program Committee members and other reviewers; all are experts in various image analysis and recognition areas. Each paper wasreviewedbyatleasttwo reviewers, andalsocheckedbythe conference Co-chairs. In all, 93 papers were ?nally accepted (45 oral presentations, and 48 posters) and appear in these proceedings. This year, di?erent from previous years, we opted for single sessions rather than parallel sessions to encourage participation in all sessions. The high quality of the papers is attributed ?rst to theauthors, andsecondtothequalityofthereviewsprovidedbytheexperts. We would like to thank the authors for responding to our call for papers, some are returningauthorswhoattendedpreviouseditionsofthe conferenceandsomeare new.

Attention has represented a core scienti?c topic in the design of AI-enabled systems in the last few decades. Today, in the ongoing debate, design, and c- putationalmodelingofarti?cialcognitivesystems, attentionhasgainedacentral position as a focus of research. For instance, attentional methods are considered in investigating the interfacing of sensory and cognitive information processing, for the organization of behaviors, and for the understanding of individual and social cognition in infant development. Whilevisualcognitionplaysacentralroleinhumanperception, ?ndingsfrom neuroscience and experimental psychology have provided strong evidence about the perception-action nature of cognition. The embodied nature of senso- motor intelligence requires a continuous and focused interplay between the c- trolofmotoractivitiesandtheinterpretationoffeedbackfromperceptualmod- ities. Decision making about the selection of information from the incoming sensory stream - in tune with contextual processing on a current task and an agent's global objectives - becomes a further challenging issue in attentional control. Attention must operate at interfaces between a bottom-up-driven world interpretationandtop-down-driveninformationselection, thusactingatthecore of arti?cial cognitive systems. These insights have already induced changes in AI-related disciplines, such as the design of behavior-based robot control and the computational modeling of animats. Today, the development of enabling technologiessuch as autonomous robotic systems, miniaturizedmobile-evenwearable-sensors, andambientintelligence systems involves the real-time analysis of enormous quantities of data. These data have to be processed in an intelligent way to provide "on time delivery" of the required relevant information. Knowledge has to be applied about what needs to be attended to, and when, and what to do in a meaningful sequence, in correspondence with visual feedback.

This book contains the best papers of the Second International Conference on So- ware and Data Technologies (ICSOFT 2007), held in Barcelona, Spain. It was org- ized by the Institute for Systems and Technologies of Information, Communication and Control (INSTICC), co-sponsored by the Workflow Management Coalition (WfMC), in cooperation with the Interdisciplinary Institute for Collaboration and Research on Enterprise Systems and Technology (IICREST). The purpose of ICSOFT 2007 was to bring together researchers and practitioners int- ested in information technology and software development. The conference tracks were "Software Engineering," "Information Systems and Data Management," "Programming Languages," "Distributed and Parallel Systems" and "Knowledge Engineering." Being crucial for the development of information systems, software and data te- nologies encompass a large number of research topics and applications: from imp- mentation-related issues to more abstract theoretical aspects of software engineering; from databases and data warehouses to management information systems and kno- edge-base systems; next to that, distributed systems, pervasive computing, data quality and other related topics are included in the scope of this conference.

This volume brings together the peer-reviewed contributions of the participants at the COST 2102 and euCognition International Training School on "Multimodal Signals: C- nitive and Algorithmic Issues" held in Vietri sul Mare, Salerno, Italy, April 22 -26, 2008. The school was sponsored by COST (European Cooperation in the Field of Scientific and Technical Research, www.cost.esf.org) in the domain of Information and Communi- tion Technologies (ICT) for disseminating the advances of the research activities developed within Action 2102: "Cross-Modal Analysis of Verbal and Nonverbal Communication" (www.cost.esf.org/domains_actions/ict/Actions/Verbal_and_Non- verbal _Communication) and by euCognition: The European Network for Advancement of Artificial Cognitive Systems (www.euCognition.org). COST Action 2102, in its second year of life, brought together about 60 European and 6 overseas scientific laboratories whose aim is to develop interactive dialogue systems and intelligent virtual avatars graphically embodied in a 2D and/or 3D int- active virtual world, able to interact intelligently with the environment, other avatars, and particularly with human users. The main theme of the school was to investigate the mathematical and psycholo- cal tools for modelling human-machine interaction through access to a graded series of tasks for measuring the amount of adjustment (as well as intelligence and achie- ment) needed for introducing new concepts in the information communication te- nology domain in order to develop adaptive, socially enabled and human-centered automatic systems able to serve remote applications in medicine, learning, care, re- bilitation, and for accessibility to work, employment, and information.

The 4th International Workshop on Medical Imaging and Augmented Reality, MIAR 2008, was held at the University of Tokyo, Tokyo, Japan during August 1-2, 2008. The goal of MIAR 2008 was to bring together researchersin medical imaging and intervention to present state-of-the-art developments in this ever-growing research area. Rapid technical advances in medical imaging, including its gr- ing application in drug/gene therapy and invasive/interventional procedures, have attracted signi?cant interest in the close integration of research in the life sciences, medicine, physical sciences, and engineering. Current research is also motivated by the fact that medical imaging is moving increasingly from a p- marily diagnostic modality towards a therapeutic and interventional aid, driven by the streamlining of diagnostic and therapeutic processes for human diseases by means of imaging modalities and robotic-assisted surgery. The impact of MIAR on these ?elds increases each year, and the quality of submitted papers this yearwas veryimpressive. We received90 full submissions, which were subsequently reviewed by up to ?ve reviewers. Reviewer a?liations were carefully checked against author a?liations to avoid con?icts of interest, and the review process was run as a double-blind process. A special procedure was also devised for papers from the universities of the organizers, upholding a double-blind review process for these papers. The MIAR 2008 Program C- mittee ?nally accepted 44 full papers. For this workshop, we also included three papers from the invited speakers coveringregistration and segmentation, virtual reality, and perceptual docking for robotic control.

The chapters in this volume were presented at the July-August 2008 NATO Advanced Study Institute on Unexploded Ordnance Detection and Mitigation. The conference was held at the beautiful Il Ciocco resort near Lucca, in the glorious Tuscany region of northern Italy. For the ninth time we gathered at this idyllic spot to explore and extend the reciprocity between mathematics and engineering. The dynamic interaction between world-renowned scientists from the usually disparate communities of pure mathematicians and applied scientists which occurred at our eight previous ASI's continued at this meeting. The detection and neutralization of unexploded ordnance (UXO) has been of major concern for very many decades; at least since the First World war. UXO continues to be the subject of intensive research in many ?elds of science, incl- ing mathematics, signal processing (mainly radar and sonar) and chemistry. While today's headlines emphasize the mayhem resulting from the placement of imp- vised explosive devices (IEDs), humanitarian landmine clearing continues to draw signi?cant global attention as well. In many countries of the world, landmines threaten the population and hinder reconstruction and fast, ef?cient utilization of large areas of the mined land in the aftermath of military con?icts.

A key driving factor for biometrics is the widespread national and international depl- ment of biometric systems that has been initiated in the past two years and is about to accelerate. While nearly all current biometric deployments are government-led and pr- cipally concerned with national security and border control scenarios, it is now apparent that the widespread availability of biometrics in everyday life will also spin out an ev- increasing number of (private) applications in other domains. Crucial to this vision is the management of the user's identity, which does not only imply the creation and update of a biometric template, but requires the development of instruments to properly handle all the data and operations related to the user identity. COST Action 2101 on Biometrics for Identity Documents and Smart Cards has - erated as a valuable and effective platform for close collaboration of European sci- tists from academia and industry researching biometrics for identity documents and smartcards. This has led to the continuous advances achieved in various classes of biometrics and their implementations in the identity management domain. These c- tributions to knowledge in this field were first presented at the First European Wo- shop on Biometrics and Identity Management (BioID 2008) organized in Roskilde, Denmark during May 7-9, 2008.

This book contains refereed and improved papers presented at the Seventh IAPR Workshop on Graphics Recognition (GREC2007), held in Curitiba, Brazil, September 20-21, 2007. The GREC workshops provide an excellent opportunity for researchers and practitioners at all levels of experience to meet colleagues and to share new ideas and knowledge about graphics recognition methods. Graphics recognition is a subfield of document image analysis that deals with graphical entities in engineering drawings, sketches, maps, architectural plans, musical scores, mathematical notation, tables, diagrams, etc. GREC2007 continued the tradition of past workshops held at Penn State University, USA (GREC 1995, LNCS Volume 1072, Springer, 1996); Nancy, France (GREC 1997, LNCS Volume 1389, Springer, 1998); Jaipur, India (GREC 1999, LNCS Volume 1941, Springer, 2000); Kingston, Canada (GREC 2001, LNCS Volume 2390, Springer, 2002); Barcelona, Spain (GREC 2003, LNCS Volume 3088, Springer, 2004); and Hong Kong, China (GREC 2005, LNCS Volume 3926, Springer, 2006). GREC2007 was also the first edition of a GREC workshop held at the same location of the ICDAR conference and it facilitated people to attend to both events. The program of GREC2007 was organized in a single-track 2-day workshop. It comprised several sessions dedicated to specific topics.

Affect and emotion play an important role in our everyday lives: They are present whatever we do, wherever we are, and wherever we go, without us being aware of them for much of the time. When it comes to interaction, be it with humans, technology, or humans via technology, we suddenly become more aware of emotion, either by seeing the other's emotional expression, or by not getting an emotional response while anticipating one.

Given this, it seems only sensible to explore affect and emotion in human-computer interaction, to investigate the underlying principles, to study the role they play, to develop methods to quantify them, and to finally build applications that make use of them. This is the research field for which, over ten years ago, Rosalind Picard coined the phrase "affective computing."

The present book provides an account of the latest work on a variety of aspects related to affect and emotion in human-technology interaction. It covers theoretical issues, user experience and design aspects as well as sensing issues, and reports on a number of affective applications that have been developed in recent years.
