Fast Integer Pixel Motion Estimation Algorithm for AVS-M
Xiaowu Li · Journal of Chinese Computer Systems · 2011
This paper poses a kind of auto-adapted motion estimation fast search algorithms based on beginning forecast and early stop in the process of integer pixel motion vector search according to the characteristic of movtion estimation in AVS-M code process.Comparing with MVFAST algorithms,this algorithms reduces greatly search points,accelerates search process,enhances average velocity to 39.9%～45.7% and reduces the computation load of integer pixel motion estimation.It maintains low code rate and high picture quality at the same time of raising the code speed.
