  • Automatic learning of 3D pose variability in walking performances for gait analysis 

    Rius, Ignasi; González Sabaté, Jordi; Mozerov, Mikhail; Roca, Francesc Xavier (2008)
    Article
    Open Access
    This paper proposes an action specific model which automatically learns the variability of 3D human postures observed in a set of training sequences. First, a Dynamic Programing synchronization algorithm is presented in ...
  • Importance of detection for video surveillance applications 

    Varona, Javier; González Sabaté, Jordi; Rius, Ignasi; Villanueva Pipaón, Juan José (2008)
    Article
    Open Access
    Though it is the first step of a real video surveillance application, detection has received less attention than tracking in research on video surveillance. We show, however, that the majority of errors in the tracking ...
  • Interpretation of complex situations in a semantic-based surveillance framework 

    Fernández, Carles; Baiget, Pau; Roca Marva, Francesc Xavier; González Sabaté, Jordi (2008)
    Article
    Open Access
    The integration of cognitive capabilities in computer vision systems requires both to enable high semantic expressiveness and to deal with high computational costs as large amounts of data are involved in the analysis. ...
  • Moving cast shadows detection methods for video surveillance applications 

    Amato, Ariel; Huerta Casado, Iván; Mozerov, Mikhail; Roca Marva, Francesc Xavier; González Sabaté, Jordi (Springer, 2013)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Moving cast shadows are a major concern in today’s performance from broad range of many vision-based surveillance applications because they highly difficult the object classification task. Several shadow detection methods ...
  • Research steps towards human sequence evaluation 

    González Sabaté, Jordi; Roca Marva, Francesc Xavier; Villanueva Pipaón, Juan José (Springer, 2009)
    Part of book or chapter of book
    Open Access
    Human Sequence Evaluation (HSE) 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 ...
  • Toward natural interaction through visual recognition of body gestures in real-time 

    Varona, Javier; Jaume Capo, Antoni; González Sabaté, Jordi; Perales Lorente, José Francisco (2009)
    Article
    Restricted access - publisher's policy
    In most of the existing human–computer interfaces, enactive knowledge as new natural interaction paradigm has not been fully exploited yet. Recent technological advances have created the possibility to enhance naturally ...
  • Trajectory occlusion handling with multiple view distance minimization clustering 

    Mozerov, Mikhail; Amato, Ariel; Roca Marva, Francesc Xavier; González Sabaté, Jordi (2008)
    Article
    Open Access
    A robust and efficient method for overcoming the negative effects of long-time occlusion in the tracking process is presented. The proposed approach is based on the matching of multiple trajectories in time. Trajectories ...
  • Understanding dynamic scenes based on human sequence evaluation 

    González Sabaté, Jordi; Rowe, Daniel; Varona, Javier; Roca, Francesc Xavier (2009)
    Article
    Open Access
    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 ...
