    • Depth estimation of frames in image sequences using motion occlusions 

      Palou Visa, Guillem; Salembier Clairon, Philippe Jean (Springer, 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 

      Palou Visa, Guillem; Salembier Clairon, Philippe Jean (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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)
      Text en actes de congrés
      Accés obert
      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)
      Tesi
      Accés obert
      When humans observe a scene, they are able to perfectly distinguish the different parts composing it. Moreover, humans can easily reconstruct the spatial position of these parts and conceive a consistent structure. The ...
    • Monocular Depth Ordering Using Occlusion Cues 

      Palou Visa, Guillem (Universitat Politècnica de Catalunya, 2011-07-01)
      Projecte Final de Màster Oficial
      Accés obert
      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 ...
    • Monocular depth ordering using T-Junctions and convexity occlusion cues

      Accés restringit per política de l'editorial
      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 ...
    • Precision-recall-classification evaluation framework: Application to depth estimation on single images 

      Palou Visa, Guillem; Salembier Clairon, Philippe Jean (Springer, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Many computer vision applications involve algorithms that can be decomposed in two main steps. In a first step, events or objects are detected and, in a second step, detections are assigned to classes. Examples of such
    • Underwater Acoustic MIMO OFDM: An experimental analysis 

      Palou Visa, Guillem (Universitat Politècnica de Catalunya, 2009-09)
      Projecte/Treball Final de Carrera
      Accés obert
      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 ...
