    • 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)

      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 ...
