Motion compensation for block-based lossless video coding using lattice-based binning

A block-based lossless video coding scheme using the notion of binning has been proposed in [1]. To further improve the compression and reduce the complexity, in this paper we investigate the impact of two sub-optimal motion search algorithms on the performance of this lattice-based scheme. While one of the algorithm tries avoiding motion vectors, the other tries to reduce complexity. Our experimental results have demonstrated that the loss due to sub-optimal motion search outweighs the gain when motion vectors are avoided. However, experimental results have shown that there is negligible performance loss when low-complexity sub-optimal three step search is used. ©2010 IEEE.
