  • Connected Operators Based On Region-Tree Pruning  
  • by Philippe Salembier, Luis Garrido — 2000 — in Proc. Int. Syrup. on Math. Morphology, Palo Alto
  • …. This paper discusses region-based representations useful to create connected operators. The filtering approach involves three steps: first, a region tree representation of the input image is constructed. Second, the simplification is obtained by pruning the tree and third, and output image is cons…

  • Region-Based Video Coding Using Mathematical Morphology  
  • by Philippe Salembier, Luis Torres, Fernand Meyer, Chuang Gu — 1995 — Proc. IEEE
  • …This paper presents a region-based coding algorithm for video sequences. The coding approach involves a time-recursive segmentation relying on the pixels homogeneity, a region-based motion estimation, and motion compensated contour and texture coding. This algorithm is mainly devoted to very low bit…

  • Extensive Operators in Partition Lattices for Image Sequence Analysis  
  • by Luis Garrido, Philippe Salembier, David Garcia — 1998 — Signal Processing
  • …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 known as connected operators and, in the second case, they are region growing te…

  • Robust Segmentation And Representation Of Foreground Key-Regions In Video Sequences  
  • by Javier Ruiz Hidalgo, Philippe Salembier — 2001 — in Proc. IEEE Intl. Conf. on Acoustics, Speech, and Signal Processing (ICASSP’01), Vol.3
  • …This paper deals with the extraction and characterization of foreground objects in video sequences. The algorithm first computes the mosaic image representing the background information and then extracts foreground objects. In this last step, the foreground objects are progressively extracted taking…

  • Visual Segment Tree Creation For Mpeg-7 Description Schemes  
  • by Philippe Salembier Joan, Joan Llach, Luis Garrido — 2000 — International Conference on Multimedia and Expo, ICME’2000, Vol 2, pp 907-910
  • …This paper deals with the creation of visual segment trees involved in MPEG-7 Description Schemes. After a brief overview of MPEG7 description schemes in general and of the Segment Description Scheme in particular, tools allowing the creation of segment trees are discussed. It is proposed to create…

  • On Filters By Reconstruction For Size And  
  • by Motion Simplification Philippe, Philippe Salembier, Javier Ruiz — 2002 — In Mathematical Morphology, Proc. of ISMM
  • …This paper deals with connected operators based on reconstruction process. New operators are proposed to perform size and motion simplification. In the case of size simplification, the proposed approach allows to better preserve the contrast of maxima or minima that have not been totally simplified …

  • MPEG-7 Multimedia Description Schemes  
  • by Philippe Salembier Member, John R. Smith — 2001 — IEEE Transactions on Circuits and Systems for Video Technology
  • …MPEG-7 Multimedia Description Schemes (MDSs) are metadata structures for describing and annotating audio-visual (AV) content. The Description Schemes (DSs) provide a standardized way of describing in XML the important concepts related to AV content description and content management in order to faci…
