1. A face detection method, comprising: acquiring a video image sequence; performing a video shot boundary detection process on the video image sequence to determine whether a shot change exists in the video image sequence to obtain a first judgment result, the video shot boundary detection process comprising: performing an image feature extraction on the video image sequence in an image feature extraction region to obtain image feature vectors of two image frames; and determining whether the two image frames are discontinuous in content, based on the image feature vectors; and determining, when the first judgment result indicates that a shot change exists in the video image sequence, that face detection has failed.
