To reduce
computational complexity and maintain the image quality,
an integer pixel fast motion estimation algorithm is proposed
in this paper. Combining the characters of the UMHexagonS
algorithm and the EPZS algorithm, the proposed algorithm
selects various searching patterns according to the motion
types of the image and introduces a early-termination
algorithm. Experimental results demonstrate that the
proposed algorithm has less ME time than FS, UMHexagonS
and EPZS algorithm with essentially the same PSNR.
