    • Antiextensive connected operators for image and sequence processing 

      Salembier Clairon, Philippe Jean; Oliveras Vergés, Albert; Garrido Ostermann, Luis (1998-04)
      Article
      Accés obert
      This paper deals with a class of morphological operators called connected operators. These operators filter the signal by merging its flat zones. As a result, they do not create any new contours and are very attractive for ...

      Salembier Clairon, Philippe Jean; Garrido Ostermann, Luis (Institute of Electrical and Electronics Engineers (IEEE), 1998)
      Text en actes de congrés
      Accés obert
      This paper discusses the interest of binary partition trees as shape-oriented image representations. Binary partition trees concentrate in a compact and structured representation a set of meaningful regions that can be ...

    • Connected operators based on region-tree pruning strategies 

      Salembier Clairon, Philippe Jean; Garrido Ostermann, Luis (Barcelona, 2000)
      Comunicació de congrés
      Accés obert
      This paper discusses region-based representations useful to create connected operators. The filtering approach involves three steps: 1) a region tree representation of the input image is constructed; 2) the simplification ...

    • Connected operators for sprite creation and layered representation of image sequences 

      Salembier Clairon, Philippe Jean; Pujol, O; Garrido Ostermann, Luis (1998)
      Text en actes de congrés
      Accés obert
      This paper proposes and discusses the use of motion-oriented connected operators for sprite creation. Motion-oriented connected operators are tools allowing the simplification of frames by removing objects that do not ...

    • Extensive operators in partition lattices for image sequence analysis 

      Garrido Ostermann, Luis; Salembier Clairon, Philippe Jean; García Vizcaíno, David (1998-04)
      Article
      Accés restringit per política de l'editorial
      This paper deals with the class of extensive operators in the lattice of partitions. These operators are merging techniques. They can be used as filtering tools or as segmentation algorithms. In the first case, they are ...

    • Image sequence analysis and merging
