Interpretation of complex situations in a semantic-based surveillance framework
Fernández, Carles; Baiget, Pau; Roca Marva, Francesc Xavier; González Sabaté, Jordi (2008)
Article
Accés obertThe 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. ... -
Natural language descriptions of human behaviour from video sequences
Fernández, Carles; Baiget, Pau; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
Capítol de llibre
Accés obertThis 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)
Text en actes de congrés
Accés obertIris 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)
Capítol de llibre
Accés obertThe 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)
Comunicació de congrés
Accés restringit per política de l'editorialModern 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)
Capítol de llibre
Accés obertA 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 ...
