Efficient Motion Estimation Algorithms for Video Coding
This work proposes an efficient motion estimation algorithm for video coding. The proposed method calculates the partial distortion by replacing a certain number pixels of each partial sub-macroblock. In addition to increase the probability of the rejection of unsuitable motion vectors without additional computations, the proposed approach reduce computational complexity significantly and obtains better objective quality than conventional motion estimation algorithms.
