Abstract
A method for determining motion vectors by employing a multi-tier hierarchical motion estimation comprises (a) motion-estimating each of the hierarchical search blocks of a processing block with respect to a corresponding hierarchical search region to thereby provide motion vectors and minimum error functions corresponding to hierarchical search blocks, (b) comparing the minimum error functions with a predetermined threshold, (c) determining a search block having a least minimum error function among the hierarchical search blocks; and (d) if minimum error functions of one or more search blocks are smaller than the predetermined threshold, determining as a motion vector of the processing block, a motion vector corresponding to a search block of a highest hierarchy among said one or more search blocks and if none of the minimum error functions are smaller than the predetermined threshold, determining a motion vector corresponding to the search block determined in said step (c) as a motion vector of the processing block.
