On reasoning over tracking events
Rowe, Daniel; Gonzàlez, Jordi; Huerta Casado, Iván; Villanueva, Juan J. (Springer, 2007)
Capítol de llibre
Accés obertHigh-level understanding of motion events is a critical task in any system which aims to analyse dynamic human-populated scenes. However, current tracking techniques still do not address complex interaction events among ... -
On-line one stroke character recognition using directional features
Al, Murad; Amato, Ariel; Sánchez, Gemma; Gonzàlez, Jordi (Springer, 2007)
Text en actes de congrés
Accés obertThis paper presents a method based on directional features for recognizing on-line characters represented by one-stroke. A new alphabet is proposed, and each character is represented as a vector of directional angles. This ... -
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 ... -
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 obertRobust 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 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 ... -
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 obertUnderstanding 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 obertState-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 obertIn 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 ...
