Claim 3:
4. The method according to claim 1, wherein the obtaining a forward displacement matrix corresponding to the first video frame and a backward displacement matrix corresponding to the second video frame based on the optical flow tracking rule, the first location information of the pixels in the first video frame, and the second location information of the pixels in the second video frame comprises:
forward mapping the pixels in the first video frame to the second video frame based on the first location information of the pixels in the first video frame and the optical flow tracking rule;
determining, in the second video frame, second location information of first mapped points obtained through the mapping, and determining the forward displacement matrix corresponding to the first video frame based on the first location information of the pixels and the second location information of the first mapped points;
backward mapping the pixels in the second video frame to the first video frame based on the second location information of the pixels in the second video frame and the optical flow tracking rule; and
determining, in the first video frame, third location information of second mapped points obtained through the mapping, and determining the backward displacement matrix corresponding to the second video frame based on the second location information of the first mapped points and the third location information of the second mapped points.
