Yang Li · Journal of Optoelectronics·laser · 2009
Motion estimation is the most computationally intensive module in an AVS-M video codecs.A new fast and efficient search algorithm for block motion estimation is proposed in this paper to reduce the computational complexity of the motion estimation.It is composed of the prediction of initial search points,adaptive search modes,and effective half-stop criteria.The algorithm well exploits the spatial-temporal correlation of the video sequences and the motion vector statistic characteristics. Experimental results show that the proposed algorithm can reduce computational complexity efficiently,while maintaining comparable search quality.
