Abstract :
A new method for coding of displaced frame differences (DFD) is proposed. DFD coding is a necessary task in hybrid video coding. In particular a Laplacian pyramid is employed which decomposes the DFD into several layers with differing spatial resolution. The pyramid is encoded in an embedded fashion using zero-trees. Simulation results show promising rate-distortion performance for low bit rate video coding
