Within an image sequence, it is not unusual that in certain local areas there exist some motions as well as illumination variations. A new method, block-matching with illumination variations (BMIV), is proposed for motion compensation in color video. For blocks with motion and illumination variations, the proposed method can estimate the motion vector and generate the associated 3/spl times/3 illumination matrix which will produce the minimal mean square error. Experiments using the proposed method show good performance.
