Paper Abstract

Quad-tree structured motion-compensation technique effectively utilizes the motion content of a frame as opposed to fixed size block motion compensation technique. In this paper, we propose a novel quad-tree-structured region-wise motion compensation technique that divides a frame into equivalent triangle blocks using the quad-tree structure. Arbitrary partition shapes are achieved by allowing 4-to-1, 3-to-1 and 2-1 merge/combine of sibling blocks having the same motion vector. We propose an optimal code scheme and a temporal predictive coding for the quad- tree. Simulation results show that our techniques reduce the bit rate by 40% as compared to other methods.
