Paper Abstract

This paper presents an innovative video coding system which processes appropriately motion information by an improved motion estimation algorithm and a segmentation based coding of displaced frame differences (DFD). The proposed multigrid motion estimation algorithm with adaptive mesh leads to more uniform and accurate motion vectors, and a lower overhead information. A morphological segmentation algorithm is proposed to code DFD by sending contours and quantized high energy regions. The method is coding oriented, and has the potential of graceful degradation. Simulation results show outstanding performances of the proposed codec for image sequences in CCIR 601 format.
