Abstract
Motion-compensated temporal filtering subband video codecs have attracted recently a lot of attention, due to their compression performance comparable with that of state-of-the-art hybrid codecs and due to their additional scalability features. In this paper, we present a scalable video codec based on a 5/3 adaptive temporal lifting decomposition. Different adaptation criteria for coping with the occluded areas are discussed and new criteria for optimizing the temporal prediction are introduced. For our simulations, we use a memory-constraint “on-the-fly” implementation. We also evaluate the temporal scalability properties of this video coding structure.
