    • 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 ...
    • Top-down model fitting for hand pose recovery in sequences of depth images 

      Madadi, Meysam; Escalera, Sergio; Carruesco Llorens, Àlex; Andújar Gran, Carlos Antonio; Baró, Xavier; Gonzàlez, Jordi (2018-11)
      Article
      Accés obert
      State-of-the-art approaches on hand pose estimation from depth images have reported promising results under quite controlled considerations. In this paper we propose a two-step pipeline for recovering the hand pose from a ...
    • 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 ...
