1. A method for extracting a target frame, comprising:
acquiring a first sequence of a set of image frames of a video arranged in positive order;
generating, based on the first sequence of a positive-order arrangement, a second sequence of the set of image frames arranged in reverse order;
determining a first cross correlation sequence of the image frames in the first sequence relative to the image frames in the second sequence;
determining a second cross correlation sequence of the image frames in the second sequence relative to the image frames in the first sequence;
determining, based on the first cross correlation sequence and the second cross correlation sequence, a global feature distribution for the set of image frames; and
determining, based on the global feature distribution, at least one target frame in the set of image frames.
