Real-time fingertip localization conditioned on hand gesture classification
Suau, Xavier; Alcoverro Vidal, Marcel; López-Méndez, Adolfo; Ruiz Hidalgo, Javier; Casas Pla, Josep Ramon (2014-05-09)
Article
Accés restringit per política de l'editorialA method to obtain accurate hand gesture classification and fingertip localization from depth images is proposed. The Oriented Radial Distribution feature is utilized, exploiting its ability to globally describe hand poses, ... -
Real-time upper body tracking with online initialization using a range sensor
López Méndez, Adolfo; Alcoverro Vidal, Marcel; Pardàs Feliu, Montse; Casas Pla, Josep Ramon (2011)
Text en actes de congrés
Accés restringit per política de l'editorialWe present a novel method for upper body pose estimation with online initialization of pose and the anthropometric profile. Our method is based on a Hierarchical Particle Filter that defines its likelihood function with ... -
Skeleton and shape adjustment and tracking in multicamera environments
Alcoverro Vidal, Marcel; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2010-07)
Article
Accés restringit per política de l'editorialIn this paper we present a method for automatic body model adjustment and motion tracking in multicamera environments.We introduce a set of shape deformation parameters based on linear blend skinning, that allow a deformation ... -
Stochastic optimization and interactive machine learning for human motion analysis
Alcoverro Vidal, Marcel (Universitat Politècnica de Catalunya, 2014-12-17)
Tesi
Accés obertThe analysis of human motion from visual data is a central issue in the computer vision research community as it enables a wide range of applications and it still remains a challenging problem when dealing with unconstrained ... -
Visual hull reconstruction algorithms comparison: towards robustness to silhouette errors
Alcoverro Vidal, Marcel; Pardàs Feliu, Montse (2009)
Text en actes de congrés
Accés obertIn this paper we review the main techniques for volume reconstruction from a set of views using Shape from Silhouette techniques and we propose a new method that adapts the inconsistencies analysis shown in (Landabaso et ...
