Abstract
We propose a new and fast full search (FS) motion estimation algorithm to reduce the amount of computation of the FS algorithm. Computational reduction of our FS motion estimation algorithm comes from fast elimination of unlikely motion vectors. We obtain faster elimination of inappropriate motion vectors using efficient matching units by localization of a complex area in the image data. In this paper, we show three properties in block matching of motion estimation. We suggest two fast matching scan algorithms, one from an adaptive matching scan and the other from fixed dithering order. The experiments show that our scheme reduces computations by about 30% compared with conventional fast FS algorithms.
