    This paper proposes a system to depth order regions of a frame belonging to a monocular image sequence. For a given frame, re- gions are ordered according to their relative depth using the previous and following frames. ...
  • Depth ordering on image sequences using motion occlusions

    This paper proposes a system to obtain the depth order of frames in image sequences using motion occlusion cues. The system first computes the forward and backward flows with the previous and next frames and estimates the ...
  • From local occlusion cues to global monocular depth estimation 

    Palou Visa, Guillem; Salembier Clairon, Philippe Jean (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report

    In this paper, we propose a system to obtain a depth ordered seg- mentation of a single image based on low level cues. The algorithm first constructs a hierarchical, region-based image representation of the image using ...
  • Hierarchical video representation with trajectory binary partition tree 

    Palou Visa, Guillem; Salembier Clairon, Philippe Jean (IEEE Computer Society Publications, 2013)
    Conference report
    Open Access
    As early stage of video processing, we introduce an iter- ative trajectory merging algorithm that produces a region- based and hierarchical representation of the video se- quence, called the Trajectory Binary Partition ...
  • Monocular depth estimation in images and sequences using occlusion cues 

    Palou Visa, Guillem (Universitat Politècnica de Catalunya, 2014-02-21)
    Doctoral thesis
  • Monocular Depth Ordering Using Occlusion Cues 

    Palou Visa, Guillem (Universitat Politècnica de Catalunya, 2011-07-01)
    Master thesis
    Open Access
    English: This project proposes a system to relate the objects in an image using occlusion cues and arrange them according to depth. The system does not rely on a priori knowledge of the scene structure and focus on detecting ...
  • Occlusion-based depth ordering on monocular images with binary partition tree 

    Palou Visa, Guillem; Salembier Clairon, Philippe Jean (2011)
    Conference report

    This paper proposes a system to relate objects in an image using occlusion cues and arrange them according to depth. The system does not rely on any a priori knowledge of the scene structure and focuses on detecting specific ...
  • Underwater Acoustic MIMO OFDM: An experimental analysis 

    Palou Visa, Guillem (Universitat Politècnica de Catalunya, 2009-09)
    Master thesis (pre-Bologna period)
    Open Access
    Research e orts over the past several years have provided ample proof that orthogonal frequency division multiplexing (OFDM) represents a viable alternative to single-carrier modulation which has traditionally been used ...
