Abstract :
Motion estimation is the process of selecting an offset to a suitable reference area in a previously coded frame. In this paper, the Predictive Motion Vector Field Adaptive Search Technique (PMVFAST) and Enhanced-PMVFAST (EPMVFAST) algorithm was reviewed, and we studied in detail the motion estimation technology in AVS in two parts: soft and hard decision process in motion estimation, soft-decision based local search pattern.
