ABSTRACT:
The present invention provides a method of adaptively selecting an optimal pixel block within an image frame. The method comprises the activity of selecting an optimal block size for fast and accurate motion estimation. The traditional block is extended into an overlapped region to form an extended pixel block. Statistical region information of the non-overlapped region and the overlapped region of the respective extended pixel block is then measured. The optimal block, either the standard (or smaller size) non-overlapped block or the boundary extended overlapped block, is then selected in response to the measured statistical region information.
