Paper Abstract

A new hybrid coding scheme for video sequences is presented. With the introduction of a fast quadtree motion segmentation algorithm, motion vectors are estimated with variable size block matching which produces better performance considering both overhead motion information and motion compensated prediction error. Small blocks containing high motion activities are intraframe vector quantized, whereas large blocks representing smooth motion areas are first decimated and then interframe vector quantized. Simulation results demonstrate that the proposed scheme performs very well.
