An adaptively refined block matching algorithm for motion compensated video coding

An adaptively refined block matching algorithm (AR-BMA) for motion compensated (MC) video coding is presented. The AR-BMA algorithm requires transmitting the same amount of motion data as the conventional block matching algorithm (BMA) while achieving much higher prediction accuracy by an adaptive refinement scheme that captures the fine motion variations in video scenes. Experimental results show significant reduction of the prediction errors by the AR-BMA as compared with the full-search BMA.<
