Title:
METHOD OF MOTION ESTIMATION FOR TRANSMISSION COST REDUCTION OF MOTION VECTORS
Document Type and Number:
WIPO Patent Application WO2000014682
Kind Code:
A3
Abstract:
The method includes segmentation of the video image into image blocks, movement estimation per image block in order to obtain a field of movement vectors. It is characterized in that it includes a stage of reassignment of a vector to a block by selecting one movement vector from among N predominant vectors belonging to the field of vectors. The applications relate to movement estimation, for example, by image-block matching.
