Abstract: Accurate motion estimation is a key factor for achieving enhanced compression ratio. It is the process of determining an offset to a suitable reference area in previously coded frame and has a significant effect on performance of coders and decoders (CODEC).This paper is survey paper for block based motion estimation. This paper describes the classical Full search motion estimation algorithm, diamond search, hexagonal search and octagon with square pattern search algorithm for motion estimation.
Keywords: Block matching, Diamond Search, Hexagonal Search, Motion Estimation, Video Coding.
Scope of the Article: Vision-based applications
