ADAPTIVE FAST SEARCH BLOCK MOTION ESTIMATION IN VIDEO COMPRESSION

摘要: With the advancement of telecommunication technologies, such as internet, video conferencing and HDTV, we need an effective compression technique. Motion estimation motion compensation are most complicated time consuming part any coding helps to reduce temporal redundancy that exists between successive frames. The codec should be that, it can computational complexity without having effect on quality video. process more efficient if use spatial correlation blocks in a frame two consecutive In this thesis, new search method for block has been presented uses neighbouring current macro-block previous same coordinates prediction vectors. proposed vectors likely helpful process. By using these centre is located, around which window placed. have introduced Sorted Search Method (SSM) algorithm compared performance with existing Block Based Estimation (BBME) techniques. Different sorting methods developed by taking different neighbours macro - their performances compared.
