      Article
      Restricted access - publisher's policy
      This paper presents a general analysis framework towards exploiting the underlying hierarchical and scalable structure of an articulated object for pose estimation and tracking. Scalable human body models are introduced ...

    • Improving detection of acoustic events using audiovisual data and feature level fusion 

      Butko, Taras; Canton Ferrer, Cristian; Segura, C.; Giró Nieto, Xavier; Nadeu Camprubí, Climent; Hernando Pericás, Francisco Javier; Casas Pla, Josep Ramon (2009)
      Conference report
      Open Access
      The detection of the acoustic events (AEs) that are naturally produced in a meeting room may help to describe the human and social activity that takes place in it. When applied to spontaneous recordings, the detection ...

    • Inclusion of video information for detection of acoustic events using the fuzzy integral 

      Butko, Taras; Temko, Andrey A.; Nadeu Camprubí, Climent; Canton Ferrer, Cristian (2008-01-01)
      Article
      Open Access
      When applied to interactive seminars, the detection of acoustic events from only audio information shows a large amount of errors, which are mostly due to the temporal overlaps of sounds. Video signals may be a useful ...

    • 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
      Open Access

    • 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)
      Conference lecture
      Open Access
      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
