  • A real-time body tracking system for smart rooms 

    Alcoverro Vidal, Marcel; López Méndez, Adolfo; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We present a real-time human body tracking system for a single user in a Smart Room scenario. In this paper we propose a novel system that involves a silhouette-based cost function using variable windows, a hierarchical ...
  • Approximate partitioning of observations in hierarchical particle filter body tracking 

    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
    This paper presents a model-based hierarchical particle filtering algorithm to estimate the pose and anthropometric parameters of humans in multi-view environments. Our method incorporates a novel likelihood measurement ...
  • 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'editorial
    This 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 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 ...
  • 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 ...
  • Models and estimators for markerless human motion tracking 

    Alcoverro Vidal, Marcel (Universitat Politècnica de Catalunya, 2009-06-25)
    Projecte Final de Màster Oficial
    Accés obert
    In 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'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 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'editorial
    A 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
