    • Multi-camera multi-object voxel-based Monte Carlo 3D tracking strategies 

      Canton Ferrer, Cristian; Casas Pla, Josep Ramon; Pardàs Feliu, Montse; Monte Moreno, Enrique (HINDAWI, 2011-11-23)
      Article
      Accés obert
      This article presents a new approach to the problem of simultaneous tracking of several people in low-resolution sequences from multiple calibrated cameras. Redundancy among cameras is exploited to generate a discrete 3D ...
    • Multi-person tracking strategies based on voxel analysis 

      Canton Ferrer, Cristian; Salvador Marcos, Jordi; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2008-06)
      Article
      Accés restringit per política de l'editorial
      This paper presents two approaches to the problem of simultaneous tracking of several people in low resolution sequences from multiple calibrated cameras. Spatial redundancy is exploited to generate a discrete 3D binary ...
    • Pixinwav: Residual steganography for hiding pixels in audio 

      Geleta Geleta, Margarita; Puntí Álvarez, Cristina; McGuinness, Kevin; Pons Puig, Jordi; Canton Ferrer, Cristian; Giró Nieto, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Comunicació de congrés
      Accés obert
      Steganography comprises the mechanics of hiding data in a host media that may be publicly available. While previous works focused on unimodal setups (e.g., hiding images in images, or hiding audio in audio), PixInWav targets ...
    • Real-time 3D multi-person tracking using Monte Carlo surface sampling 

      Canton Ferrer, Cristian; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2010)
      Text en actes de congrés
      Accés obert
      The current paper presents a low-complexity approach to the problem of simultaneous tracking of several people in low resolution sequences from multiple calibrated cameras. Redundancy among cameras is exploited to ...
    • Spatio-temporal alignment and hyperspherical radon transform for 3D gait recognition in multi-view environments 

      Canton Ferrer, Cristian; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2010)
      Text en actes de congrés
      Accés obert
      This paper presents a view-invariant approach to gait recognition in multi-camera scenarios exploiting a joint spatio-temporal data representation and analysis. First, multi-view information is employed to generate a 3D ...
    • Towards a low cost multi-camera marker based human motion capture system 

      Canton Ferrer, Cristian; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2009-11)
      Comunicació de congrés
      Accés obert
      This paper presents a low cost real-time alternative to available commercial human motion capture systems. First, a set of distinguishable markers are placed on several human body landmarks and the scene is captured by a ...
    • 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 ...
    • Voxel based annealed particle filtering for markerless 3D articulated motion capture 

      Canton Ferrer, Cristian; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (IEEE Press. Institute of Electrical and Electronics Engineers, 2009-06)
      Text en actes de congrés
      Accés obert
      This paper presents a view-independent approach to markerless human motion capture in low resolution sequences from multiple calibrated and synchronized cameras. Redundancy among cameras is exploited to generate a 3D ...
