Video Coding with Lifted Wavelet Transforms and Frame-Adaptive Motion Compensation

This paper investigates video coding with wavelet transforms applied in the temporal direction of a video sequence. The wavelets are implemented with the lifting scheme in order to permit motion compensation between successive pictures. We generalize the coding scheme and permit motion compensation from any even picture in the GOP by maintaining the invertibility of the inter-frame transform. We show experimentally, that frame-adaptive motion compensation improves the compression efficiency of the Haar and 5/3 wavelet.
