    • Feature-based annealing particle filter for robust body pose estimation 

      López Méndez, Adolfo; Casas Pla, Josep Ramon (2009-02)
      Text en actes de congrés
      Accés obert
      This paper presents a new annealing method for particle filtering in the context of body pose estimation. The feature-based annealing is inferred from the weighting functions obtained with common image features used for ...

    • Feature-based annealing particle filter for robust motion capture 

      López Méndez, Adolfo (Universitat Politècnica de Catalunya, 2009-03-02)
      Projecte Final de Màster Oficial
      Accés obert
      This thesis presents a new annealing method for particle filtering aiming at body pose estimation. Particle filters are Monte Carlo methods commonly employed in non-linear and non-Gaussian Bayesian problems, such as the ...

    • 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 obert
      In 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 ...

    • Human Motion Analysis Module 

      López Méndez, Adolfo; Casas Pla, Josep Ramon (2009-10-09)
      Report de recerca
      Accés restringit per acord de confidencialitat
      This document presents the implemented algorithms for human motion analysis within ACTIBIO. According to the systems developed in WP3 two main branches of analysis have been defined: model-based and model-free analysis. ...

    • 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'editorial
      In 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 ...

    • Metric learning from poses for temporal clustering of human motion 

      López Méndez, Adolfo; Gall, Juergen; Casas Pla, Josep Ramon; van Gool, Luc (2012)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Temporal clustering of human motion into semantically meaningful behaviors is a challenging task. While unsupervised methods do well to some extent, the obtained clusters often lack a semantic interpretation. In this paper, ...

    • 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'editorial
      In 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 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'editorial
      We 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 ...

    • Research and state-of-the-art algorithms of event-related activities for human monitoring 

      López Méndez, Adolfo; Casas Pla, Josep Ramon (2009-03-01)
      Report de recerca
      Accés restringit per acord de confidencialitat
      In this report we analyze state-of-the-art algorithms for human monitoring in generic environments and we focus on video monitoring of human activity. The objective is to define the basis upon which the ACTIBIO dataset ...

    • Research on state-of-the art algorithms for Human detection and tracking in controlled environments and recommendations for system development 

      López Méndez, Adolfo; Casas Pla, Josep Ramon; Huang, Xiaxi; Boulgouris, Nicolaos V. (2008-11-01)
      Report de recerca
      Accés restringit per acord de confidencialitat
      The present document aims at reviewing the state-of-the-art algorithms for human detection and tracking that are relevant to ACTIBIO objectives. The document is split into two main parts: Human Detection and Human Body Tracking

    • Virtual view appearance representation for human motion analysis in multi-view environments 

      López Méndez, Adolfo; Canton Ferrer, Cristian; Casas Pla, Josep Ramon (2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We propose a view-invariant representation of human appearance in multi-view scenarios consisting in a new set of views that overcome the view-dependency and moderate occlusion problems of fixed cameras. First, a 3D ...
