Claim 1:
2. The method of claim 1, wherein determining the wrinkle points from all the pixel points of each to-be-detected image of the plurality of to-be-detected images based on the grayscale values of the pixel points in each to-be-detected image of the plurality of to-be-detected images comprises:
setting a rectangular window;
controlling, according to a specified sliding step, the rectangular window to traverse each to-be-detected image of the plurality of to-be-detected images;
determining, at each window position in which the rectangular window is located, a central pixel point located at a central position of the rectangular window, and determining a confidence value of the central pixel point based on grayscale values of all pixel points in the rectangular window, to obtain a plurality of confidence values, wherein each confidence value indicates a possibility that the central pixel point is the wrinkle point; and
using a central pixel point corresponding to a confidence value not less than a threshold as the wrinkle point.
