Uniform motion-compensated 5/3 filterbank for subband video coding

Motion-compensated temporal filtering is an essential ingredient of recently developed wavelet-based scalable video coding schemes. Lifting implementation of these decompositions represents a versatile tool for spatio-temporal optimizations and numerous improvements have thus been proposed. In this paper, we propose an alternative structure for the temporal prediction in the 5/3 filterbank. It significantly reduces the ghosting artefacts in the temporal approximation subband frames, providing a higher quality scalability and improved compression performance, for an equivalent complexity.
