An efficient merge-based algorithm for variable-size block matching ME (motion estimation) to reduce the computation of block-size decision process in H264 video encoder is proposed Fixed-size 4 /spl times/ 4 small blocks are used for the integer-pixel accuracy full search ME and several candidate MVs are reserved for each 4 /spl times/ 4 blocks to determined if the neighboring blocks could be merge into other predefined block types or not Simulation result shows the computational load of our method is significantly reduced than H264 JM 73read more
