Research of motion estimation algorithm based on H.264

摘要

Through the study on the existing motion estimation algorithms, for the problems existed in them, this paper improves the motion estimation algorithm. The improved algorithm reduces the complexity of the motion search algorithm through pre-judgment of motion types, dynamic selection of motion search patterns, early end of the search process and other technologies, which avoids the block matching calculation for some points with small probability, thus to achieve the purpose of reducing the complexity of the whole motion estimation algorithm, to improve the algorithm efficiency.
