ABSTRACT

In this chapter, the authors address the issue of video sequence compression and define the concepts of image and video sequences. They also address the issue of interframe correlation between successive frames. The authors discuss two techniques in exploitation of interframe correlation, frame replenishment, and motion-compensated coding. They also discuss the concepts of motion analysis and motion compensation in general. The authors also define the concept of various image sequences in a theoretical and systematic manner. The increased computational complexity and memory space associated with image sequence processing are becoming more affordable due to more advanced, achievable computational capability. The major difference lies in the exploitation of interframe correlation that exists between successive frames in video sequences in addition to the intraframe correlation that exists within each frame. There are two major techniques in exploitation of interframe correlation: frame replenishment and motion compensation.
