Motion-compensated Video Coding Techniques

The ever-increasing demands of the modern telemetry system for the transmission of high resolution digital video data at primary and sub-primary bit rates necessitate the employment of efficient motion-compensated video coding algorithms. This paper reviews the current status of motion compensation techniques. The two major classes of motion estimation methods currently being used for predictiv...

Video coding with superimposed motion compensated signals

Motion compensated Prediction in Distributed Video Coding

The ongoing research in Distributed Video Coding (DVC) for low complexity encoding is trying to shorten the substantial performance gap to well known state-of-the-art coders. One of the reasons for this gap is the motion estimation without the reference frame. In this paper we look at what motion estimation to use. Furthermore we compare the two possible methods to get a motion compensated pred...

Efficiency analysis of multihypothesis motion-compensated prediction for video coding

Overlapped block motion compensation or B-frames are examples of multihypothesis motion compensation where several motion-compensated signals are superimposed to reduce the bit-rate of a video codec. This paper extends the wide-sense stationary theory of motion-compensated prediction (MCP) for hybrid video codecs to multihypothesis motion compensation. The power spectrum of the prediction error...

Motion Compensated Two-link Chain Coding for Binary Shape Sequences

In this paper, we present a motion compensated twolink chain coding technique to effectively encode 2-D binary shape sequences for object-based video coding. This technique consists of a contour motion estimation and compensation algorithm and a two-link chain coding algorithm. The object contour is defined on a 6-connected contour lattice for a smoother contour representation. The contour in t...
