ABSTRACT:
A block-matching method for generating motion vectors performs block matching on successively higher resolution images by refining motion vectors determined in a lower resolution image. At respective higher resolution images, search areas of limited search range are defined via a motion vector associated with corresponding image areas in the immediately lower resolution search. For at least one level of image resolution, the search blocks are overlapped to provide a plurality of search areas of limited search range for performing block matching searches for each block in the next higher resolution level.
