Connected Operators on 3D data for human body analysis
Alcoverro Vidal, Marcel; López Méndez, Adolfo; Pardàs Feliu, Montse; Casas Pla, Josep Ramon (2011)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a novel method for filtering and extraction of human body features from 3D data, either from multi-view images or range sensors. The proposed algorithm consists in processing the geodesic distances on ... -
Gesture control interface for immersive panoramic displays
Alcoverro Vidal, Marcel; Suau, Xavier; Morros Rubió, Josep Ramon; López Méndez, Adolfo; Gil, Albert; Ruiz Hidalgo, Javier; Casas Pla, Josep Ramon (2013-07-25)
Article
Accés obertIn this paper, we propose a gesture-based interface designed to interact with panoramic scenes. The system combines novel static gestures with a fast hand tracking method. Our proposal is to use static gestures as shortcuts ... -
INTAIRACT: Joint hand gesture and fingertip classification for touchless interaction
Suau Cuadros, Xavier; Alcoverro Vidal, Marcel; López Méndez, Adolfo; Ruiz Hidalgo, Javier; Casas Pla, Josep Ramon (Springer, 2012)
Comunicació de congrés
Accés restringit per política de l'editorialIn this demo we present intAIRact, an online hand-based touchless interaction system. Interactions are based on easy-to-learn hand gestures, that combined with translations and rotations render a user friendly and highly ... -
Models and estimators for markerless human motion tracking
Alcoverro Vidal, Marcel (Universitat Politècnica de Catalunya, 2009-06-25)
Projecte Final de Màster Oficial
Accés obertIn this work, we analyze the diferent components of a model-based motion tracking system. The system consists in: a human body model, an estimator, and a likelihood or cost function. -
Multi-view body tracking with a detector-driven hierarchical particle filter
Navarro, S.; López Méndez, Adolfo; Alcoverro Vidal, Marcel; Casas Pla, Josep Ramon (Springer, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper we present a novel approach to markerless human motion capture that robustly integrates body part detections in multiple views. The proposed method fuses cues from multiple views to enhance the propagation ... -
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 ...
