Motion compensation method for use in an image encoding system

摘要

A method capable of improving the image quality comprises the steps of (a) detecting a motion vector for each search block in the current frame by using a block matching algorithm, (b) dividing a search block into a central region positioned at the center of the search block and a boundary region located outside the central region, (c) determining the motion vector for the search block as an optimum motion vector for the central region, and (d) determining a multiplicity of optimum motion vectors for the boundary region of the search block based on motion vectors for the search block and its one or more adjacent search blocks.
