  • Natural language descriptions of human behaviour from video sequences 

    Fernández, Carles; Baiget, Pau; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
    Part of book or chapter of book
    Open Access
    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 ...
  • New approaches for iris boundary localization 

    Pérez, Dídac; Fernández, Carles; Segura, Carlos; Hernando Pericás, Francisco Javier (Universidad de las Palmas de Gran Canarias, 2012)
    Conference report
    Open Access
    Iris segmentation is the most determining factor in iris biometrics, which has traditionally assumed rigid constrained environments. In this work, a novel method that covers the localization of the pupillaty and limbic ...
  • Ontology for semantic integration in a cognitive surveillance system 

    Fernández, Carles; Gonzàlez, Jordi (Springer, 2007)
    Part of book or chapter of book
    Open Access
    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 ...
  • Real-time GPU-based face detection in HD video sequences 

    Oro, David; Fernández, Carles; Rodriguez Saeta, Javier; Martorell Bofill, Xavier; Hernando Pericás, Francisco Javier (2011)
    Conference lecture
    Restricted access - publisher's policy
    Modern GPUs have evolved into fully programmable parallel stream multiprocessors. Due to the nature of the graphic workloads, computer vision algorithms are in good position to leverage the computing power of these ...
  • Semantic annotation of complex human scenes for multimedia surveillance 

    Fernández, Carles; Baiget, Pau; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
    Part of book or chapter of book
    Open Access
    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 ...
