Abstract

Motion estimation and compensation are important tasks in image sequence coding. In this paper, we present a motion estimation scheme with multiresolution tree structure and hierarchical motion vector search. Experiments and analysis show that this scheme is not only computation efficient, but also robust. The multiresolution tree structure is further utilized in a variable block size image sequence coding scheme that incorporates the visual spatio-temporal characteristics. Both DCT and quadtree approaches are used to encode the motion compensated prediction error. Although the signal-to-noise ratio of the quadtree coded image is a little lower, the subjective quality around sharp edges is much better. Comparing our extensive simulation results with the MPEG-1 standard, we have obtained quite promising results.
