    • A segmentation-based coding system allowing manipulation of objects (sesame) 

      Marqués Acosta, Fernando; Salembier Clairon, Philippe Jean; Pardàs Feliu, Montse; Marcotegui Iturmendi, Beatriz (IEEE, 1996)
      Conference report
      Open Access
      We present a coding scheme that achieves, for each image in the sequence, the best segmentation in terms of rate-distortion theory. It is obtained from a set of initial regions and a set of available coding techniques. The ...
    • A video object generation tool allowing friendly user interaction 

      Marcotegui Iturmendi, Beatriz; Correia Fernandez-Pereira, Paulo; Marqués Acosta, Fernando; Mech, R.; Rosa, R; Wollborn, M; Zanoguera, Francisca (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Conference report
      Open Access
      In this paper we describe an interactive video object segmentation tool developed in the framework of the ACTS-AC098 MOMUSYS project. The Video Object Generator with User Environment (VOGUE) combines three different sets ...
    • Allowing content-based functionalities in segmentation-based coding schemes 

      Marcotegui Iturmendi, Beatriz; Marqués Acosta, Fernando; Meyer, F (1997-08)
      Article
      Open Access
      This paper deals with the use of the segmentation tools and principles presented in [10] and [13] for allowing content-based functionalities. In this framework, means for supervised selection of objects in the scene are ...
    • Partition-based image representation as basis for user-assisted segmentation 

      Marqués Acosta, Fernando; Marcotegui Iturmendi, Beatriz; Zanoguera, Francisca; Correia Fernandez-Pereira, Paulo; Mech, R.; Wollborn, M (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      Conference report
      Open Access
      This paper discusses the usefulness of a partition-based image representation in the context of user-assisted segmentation, and compares it with the two other most common image representations in this framework: pixel-based ...
    • 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
      Open Access
      This paper deals with the relation between segmentation for coding and rate control. The efficiency of a segmentation-based coding scheme heavily relies on this step that defines how many and which regions have to be ...
    • 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 ...
