Document Type and Number:
Japanese Patent JPH10507331
Kind Code:
A
Abstract:
The invention relates to an image sequence coding method comprising a segmentation of each image into partitions made of regions, an estimation and compensation of the motion of these regions between two partitions, and a region contour and texture coding step. The proposed motion estimation step of this method is carried out in a loop circuit (91, 92) in which, after a definition of the mode of transmission of the regions, a particular coded signal is generated for the background regions of the partition, said signal including an order information, indicating a priority between contiguous regions, and an associated updated motion information. The implementation of this method reduces drastically the computational load before the contour coding. The invention also relates to the corresponding decoding method and system.
