Abstract :
The concept of high-order motion compensation is introduced. It is argued that in hybrid video coding, motion-compensated prediction has to be viewed as a source coding problem with a fidelity criterion. Based on our considerations, various high-order motion compensation approaches are presented that achieve significantly improved video coding results. The designed motion-compensated predictors achieve gains by exploiting high-order statistical dependencies in the video signal.
