Paper Abstract

A hybrid video compression scheme is reviewed and the incorporation of the concept of regions of interest into this scheme is investigated. The employed DFD coding method is in its main aspects close to the classical pyramid approach of Burt and Adelson. In particular a centered least squares Laplacian pyramid is used which decomposes the DFD into several levels with differing spatial resolution. This pyramid is quantized and coded following a layered quantization approach together with a layered coding method based on conditional arithmetic coding. The DFD encoder outputs an embedded bit stream. Thus the coder control may truncate the bitstream at any point,a nd can keep a fixed rate. SImulation results show that incorporation of regions of interest can further improve the rate-distortion performance for low bit rate video coding.
