Abstract

A new region-based coding scheme is introduced. It uses generalized parabolic blending curves for contour coding which lead to visually preferable smooth contours and support good local controllability. A rate-distortion criterion is applied to decide which regions should be used for motion compensation and for optimizing the region contours. The conditions for optimal regions in a rate-distortion sense are derived. Simulation results are presented. A gain of about 2 dB in PSNR for region-based motion compensation with optimized regions over block-based motion compensation at very low bit-rates is reported.
