Claim 5:
6. The method according to claim 5, wherein the determining the weight distribution map of the reference sub-region comprises:
performing normalization processing on the pixels in the reference sub-region to obtain probability values that the pixels in the reference sub-region belong to the reference sub-region;
performing binarization processing on the initial feature values of the pixels in the reference sub-region according to the probability values of the pixels in the reference sub-region and a probability threshold, to obtain a mask of the reference sub-region, the mask comprising feature values of the pixels in the reference sub-region after the binarization processing; and
calculating a product of the weight of the reference sub-region and the mask to obtain the weight distribution map of the reference sub-region.
