Abstract£oAiming at the higher bit?arate occupation of motion vector encoding and more time load of full?asearching strategies, a multi-resolution motion estimation and compensation algorithm based on adjacent prediction of frame difference was proposed. Differential motion detection was employed to image sequences and proper threshold was ad opted to identify the connected region. Then the motion region was extracted to carry out motion estimation and motion compensation on it£?The experiment results show that the encoding efficiency of motion vector is promoted, the complexity of motion estimation is reduced and the quality of the reconstruction image at the same bit-rate as Multi-Resolution Motion Estimation(MRME)is improved.
