    • HERMES: A research project on human sequence evaluation 

      Gonzàlez, Jordi; Roca, Francesc Xavier; Villanueva, Juan J. (Taylor and Francis, 2007)
      Text en actes de congrés
      Accés obert
      Human Sequence Evaluation concentrates on how to extract descriptions of human behaviour from videos in a restricted discourse domain, such as (i) pedestrians crossing inner-city roads where pedestrians appear approaching ...
    • Hierarchical eyelid and face tracking 

      Orozco, Francisco J.; Gonzàlez, Jordi; Rius, Ignasi; Roca, Francesc Xavier (Springer Verlag, 2007)
      Capítol de llibre
      Accés obert
      Most applications on Human Computer Interaction (HCI) require to extract the movements of user faces, while avoiding high memory and time expenses. Moreover, HCI systems usually use low-cost cameras, while current face ...
    • High-level integration for cognitive vision surveillance 

      Fernández, Carles; Baiget, Pau; Roca, Francesc Xavier; Gonzàlez, Jordi (s. n., 2007)
      Text en actes de congrés
      Accés obert
      The increasing interest in Cognitive Vision Systems (CVS) motivates the apparition of ad-hoc stages designed for the integration of multiple kinds of knowledge. This paper proposes a novel ontology to restrict and integrate ...
    • Natural language descriptions of human behaviour from video sequences 

      Fernández, Carles; Baiget, Pau; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
      Capítol de llibre
      Accés obert
      This contribution addresses the generation of textual descriptions in several natural languages for evaluation of human behavior in video sequences. The problem is tackled by converting geometrical information extracted ...
    • Real-time gaze tracking with appearance-based models 

      Orozco, Francisco Javier; Roca, Francesc Xavier; González, Jordi (2009)
      Article
      Accés obert
      Psychological evidence has emphasized the importance of eye gaze analysis in human computer interaction and emotion interpretation. To this end, current image analysis algorithms take into consideration eye-lid and iris ...
    • Semantic annotation of complex human scenes for multimedia surveillance 

      Fernández, Carles; Baiget, Pau; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
      Capítol de llibre
      Accés obert
      A Multimedia Surveillance System (MSS) is considered for automatically retrieving semantic content from complex outdoor scenes, involving both human behavior and traffic domains. To characterize the dynamic information ...
    • Study of odor episodes using analytical and modeling approaches 

      Soriano Ortiz, Cecilia; Roca, Francesc Xavier; Alarcón Jordán, Marta (2004)
      Working paper
      Accés obert
    • Understanding dynamic scenes based on human sequence evaluation 

      González Sabaté, Jordi; Rowe, Daniel; Varona, Javier; Roca, Francesc Xavier (2009)
      Article
      Accés obert
      In this paper, a Cognitive Vision System (CVS) is presented, which explains the human behaviour of monitored scenes using naturallanguage texts. This cognitive analysis of human movements recorded in image sequences is ...
