Scalable wavelet video coding using long-term memory motion-compensated prediction

Temporal redundancies are the key to high compression ratios in video coding. In order to improve the prediction gain of motion compensation the concept of long-term memory motion- compensated prediction has been developed. More frames than the previously decoded frame can be taken into account for motion compensation. Usually the motion is estimated in the encoder, where all unencoded frames are accessible. We investigate the applicability of long-term memory motion- compensated prediction to a scalable wavelet video coding scheme using backward motion compensation, where the motion is estimated in both, the encoder and the decoder.
