  • Robust multiple-people tracking using color-based particle filters 

    Rowe, Daniel; Huerta Casado, Iván; Gonzàlez, Jordi; Villanueva, Juan J. (Springer Verlag, 2007)
    Capítol de llibre
    Accés obert
    Robust and accurate people tracking is a key task in many promising computer-vision applications. One must deal with non-rigid targets in open-world scenarios, whose shape and appearance evolve over time. Targets may ...
  • 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 ...
  • Spatio-temporal reasoning for reliable facial expression interpretation 

    Orozco, Francisco J.; García, Fabio A.; Arcos, Lluis; Gonzàlez, Jordi (Bielefeld University, 2007)
    Text en actes de congrés
    Accés obert
    Understanding human behaviours and emotions has received contributions from image analysis and pattern recognition techniques in order to tackle this challenge. The most popular facial expression classifiers deal with ...
  • Trajectory fusion for multiple camera tracking 

    Amato, Ariel; Al, Murad; Mozerov, Mikhail; Gonzàlez, Jordi (Springer, 2007)
    Capítol de llibre
    Accés obert
    In this paper we present a robust and efficient method to overcome the negative effects of occlusion in the tracking process of multiple agents. The proposed approach is based on the matching of multiple trajectories from ...
  • Trajectory occlusion handling with multiple view distance minimization clustering 

    Mozerov, Mikhail; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (S P I E - International Society for Optical Engineering, 2008)
    Article
    Accés obert
    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 ...
