A simple method of multiple camera calibration for the joint top view projection
Mozerov, Mikhail; Amato, Ariel; Al, Murad; Gonzàlez, Jordi (Springer, 2007)
Capítol de llibre
Accés obertA simple method for multiple camera calibration based on a novel geometric derivation is presented. The main advantage of this method is that it uses only three points in the world coordinate system to achieve the calibration. ... -
Computationally efficient graph matching via energy vector extraction
Amato, Ariel; Al, Murad; Lladós, Josep; Gonzàlez, Jordi (Springer, 2007)
Text en actes de congrés
Accés obertThis paper presents a method for graph matching based on domain knowledge by quantifying representative graph features. Our method searches and extracts the most relevant cues in different graphs. Once these cues are ... -
Constructing a path database for scene categorization
Baiget, Pau; Fernández, Carles; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (s. n., 2007)
Text en actes de congrés
Accés obertHuman behavior understanding in image sequences requires to study human interaction with the environment, because human beings behave depending on their location. Therefore, a semantic labeling of the scenario must be ... -
Exploiting multiple cues in motion segmentation based on background subtraction
Huerta Casado, Iván; Amato, Ariel; Roca Marva, Francesc Xavier; González, Jordi (2013)
Article
Accés obertThis paper presents a novel algorithm for mobile-object segmentation from static background scenes, which is both robust and accurate under most of the common problems found in motion segmentation. In our first contribution, ... -
Face detection in color images using primitive shape features
Al, Murad; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (Springer, 2007)
Capítol de llibre
Accés obertFace detection is a primary step in many applications such as face recognition, video surveillance, human computer interface, and expression recognition. Many existing detection techniques suffer under scale variation, ... -
Finding faces in color images through primitive shape features
Al, Murad; Orozco, Francisco J.; Amato, Ariel; Roca, Francesc Xavier; Gonzàlez, Jordi (s. n., 2007)
Text en actes de congrés
Accés obertFace detection is a primary step in many applications such as face recognition, video surveillance, human computer interface, and expression recognition. Many existing detection techniques suffer under scale variation, ... -
Moving cast shadows detection methods for video surveillance applications
Amato, Ariel; Huerta Casado, Iván; Mozerov, Mikhail; Roca Marva, Francesc Xavier; González Sabaté, Jordi (Springer, 2013)
Capítol de llibre
Accés restringit per política de l'editorialMoving cast shadows are a major concern in today’s performance from broad range of many vision-based surveillance applications because they highly difficult the object classification task. Several shadow detection methods ... -
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 ... -
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 ... -
Trajectory occlusion handling with multiple view distance minimization clustering
Mozerov, Mikhail; Amato, Ariel; Roca Marva, Francesc Xavier; González Sabaté, Jordi (2008)
Article
Accés obertA 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 ...
