Adaptive models for the recognition of human gesture

Thesis (Ph.D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2000.Includes bibliographical references (leaves 135-140).Tomorrow's ubiquitous computing environments will go beyond the keyboard, mouse and monitor paradigm of interaction and will require the automatic interpretation of human motion using a variety of sensors including video cameras. I present several techniques for human motion recognition that are inspired by observations on human gesture, the class of communicative human movement. Typically, gesture recognition systems are unable to handle systematic variation in the input signal, and so are too brittle to be applied successfully in many real-world situations. To address this problem, I present modeling and recognition techniques to adapt gesture models to the situation at hand. A number of systems and frameworks that use adaptive gesture models are presented. First, the parametric hidden Markov model (PHMM) addresses the representation and recognition of gesture families, to extract how a gesture is executed. Second, strong temporal models drawn from natural gesture theory are exploited to segment two kinds of natural gestures from video sequences. Third, a realtime computer vision system learns gesture models online from time-varying context. Fourth, a realtime computer vision system employs hybrid Bayesian networks to unify and extend the previous approaches, as well as point the way for future work.by Andrew David Wilson.Ph.D

Measuring Behavior 2018 Conference Proceedings

These proceedings contain the papers presented at Measuring Behavior 2018, the 11th International Conference on Methods and Techniques in Behavioral Research. The conference was organised by Manchester Metropolitan University, in collaboration with Noldus Information Technology. The conference was held during June 5th – 8th, 2018 in Manchester, UK. Building on the format that has emerged from previous meetings, we hosted a fascinating program about a wide variety of methodological aspects of the behavioral sciences. We had scientific presentations scheduled into seven general oral sessions and fifteen symposia, which covered a topical spread from rodent to human behavior. We had fourteen demonstrations, in which academics and companies demonstrated their latest prototypes. The scientific program also contained three workshops, one tutorial and a number of scientific discussion sessions. We also had scientific tours of our facilities at Manchester Metropolitan Univeristy, and the nearby British Cycling Velodrome. We hope this proceedings caters for many of your interests and we look forward to seeing and hearing more of your contributions

The Thirty Kilometre Zone

The Thirty Kilometre Zone\u27 is about a man who becomes lost in the shadows of an unspeakable and unvoiced past, who sets off into the core of his mother\u27s secrets with the hope of somehow finding a way out of the traumatic cycles that have defined them both. Through a parallel narrative, long-eluded memories overtake his mother\u27s dying mind, the very past shielded by a silence meant to save her son from sorrow. The themes of Chornobyl and Stalin\u27s Famine-Genocides are interwoven through a mainly contemporary setting. After the accident at Chornobyl, Ukraine, authorities defined the fallout field by means of three successive contamination zones extending from the power plant. The radioactive environment has been termed the exclusion zone, the alienation zone, or the thirty kilometer zone. It is this motif that informs both the narrative\u27s themes and title

IberSPEECH 2020: XI Jornadas en Tecnología del Habla and VII Iberian SLTech

IberSPEECH2020 is a two-day event, bringing together the best researchers and practitioners in speech and language technologies in Iberian languages to promote interaction and discussion. The organizing committee has planned a wide variety of scientific and social activities, including technical paper presentations, keynote lectures, presentation of projects, laboratories activities, recent PhD thesis, discussion panels, a round table, and awards to the best thesis and papers. The program of IberSPEECH2020 includes a total of 32 contributions that will be presented distributed among 5 oral sessions, a PhD session, and a projects session. To ensure the quality of all the contributions, each submitted paper was reviewed by three members of the scientific review committee. All the papers in the conference will be accessible through the International Speech Communication Association (ISCA) Online Archive. Paper selection was based on the scores and comments provided by the scientific review committee, which includes 73 researchers from different institutions (mainly from Spain and Portugal, but also from France, Germany, Brazil, Iran, Greece, Hungary, Czech Republic, Ucrania, Slovenia). Furthermore, it is confirmed to publish an extension of selected papers as a special issue of the Journal of Applied Sciences, “IberSPEECH 2020: Speech and Language Technologies for Iberian Languages”, published by MDPI with fully open access. In addition to regular paper sessions, the IberSPEECH2020 scientific program features the following activities: the ALBAYZIN evaluation challenge session.Red Española de Tecnologías del Habla.

Segmentation sémantique des contenus audio-visuels

Dans ce travail, nous avons mis au point une méthode de segmentation des contenus audiovisuels applicable aux appareils de stockage domestiques pour cela nous avons expérimenté un système distribué pour l’analyse du contenu composé de modules individuels d’analyse : les Service Unit. L’un d’entre eux a été dédié à la caractérisation des éléments hors contenu, i.e. les publicités, et offre de bonnes performances. Parallèlement, nous avons testé différents détecteurs de changement de plans afin de retenir le meilleur d’entre eux pour la suite. Puis, nous avons proposé une étude des règles de production des films, i.e. grammaire de films, qui a permis de définir les séquences de Parallel Shot. Nous avons, ainsi, testé quatre méthodes de regroupement basées similarité afin de retenir la meilleure d’entre elles pour la suite. Finalement, nous avons recherché différentes méthodes de détection des frontières de scènes et avons obtenu les meilleurs résultats en combinant une méthode basée couleur avec un critère de longueur de plan. Ce dernier offre des performances justifiant son intégration dans les appareils de stockage grand public.In this work we elaborated a method for semantic segmentation of audiovisual content applicable for consumer electronics storage devices. For the specific solution we researched first a service-oriented distributed multimedia content analysis framework composed of individual content analysis modules, i.e. Service Units. One of the latter was dedicated to identify non-content related inserts, i.e. commercials blocks, which reached high performance results. In a subsequent step we researched and benchmarked various Shot Boundary Detectors and implement the best performing one as Service Unit. Here after, our study of production rules, i.e. film grammar, provided insights of Parallel Shot sequences, i.e. Cross-Cuttings and Shot-Reverse-Shots. We researched and benchmarked four similarity-based clustering methods, two colour- and two feature-point-based ones, in order to retain the best one for our final solution. Finally, we researched several audiovisual Scene Boundary Detector methods and achieved best results combining a colour-based method with a shot length based criteria. This Scene Boundary Detector identified semantic scene boundaries with a robustness of 66% for movies and 80% for series, which proofed to be sufficient for our envisioned application Advanced Content Navigation
