Abstract :
A motion compensated video coding technique is discussed where square macro-blocks in the coding process are replaced by arbitrary shaped regions. Different components of this technique are presented in detail, such as: segmentation, region shape coding, motion estimation, and mode decisions. Simulation results show good quality images with sharper details achieved at bitrates as low as 9.6 Kb/s
