Motion Analysis and Motion Compensation

ByYun Q. Shi, Huifang Sun

This chapter addresses the issue of video sequence compression. It also discusses the concept of various image sequences is defined in a theoretical and systematic manner. Since the early 1980s, digital image sequence processing has been an attractive research area. The chapter discusses use image compression to indicate still image compression, and video compression to indicate video sequence compression. Video compression has its own characteristics; however, these make it quite different from still image compression. The major difference lies on the exploitation of interframe correlation that exists between successive frames in video sequences in addition to the intraframe correlation that exists within each frame. In the first real demonstration was presented and was termed conditional replenishment. The main drawback associated with the frame replenishment technique is that it is difficult to handle frame sequences containing more rapid changes. When there are more rapid changes, the number of pixels whose intensity values need to be updated increases.
