    Marqués Acosta, Fernando; Gasull Llampallas, Antoni (1991)
    Conference report
    Open Access
    A coding oriented image segmentation algorithm is presented. This new method is based on Gibbs-Markov Random Fields (GMRF) for contourn information, a stationary gaussian model for region interna! information, and a ...
  • Segmentation-based video coding system allowing the manipulation of objects 

    Salembier Clairon, Philippe Jean; Marqués Acosta, Fernando; Pardàs Feliu, Montse; Morros Rubió, Josep Ramon; Corset, I; Jeannin, S; Bouchard, L; Meyer, F; Marcotegui Iturmendi, Beatriz (1997-02)
    Article
    Open Access
    This paper presents a generic video coding algorithm allowing the content-based manipulation of objects. This manipulation is possible thanks to the definition of a spatiotemporal segmentation of the sequences. The coding ...
  • Segmentation of video sequences and rate control 

    Marcotegui Iturmendi, Beatriz; Marqués Acosta, Fernando; Morros Rubió, Josep Ramon; Pardàs Feliu, Montse; Salembier Clairon, Philippe Jean (1997-08)
    Article
