Abstract

The present invention relates to a key frame acquisition method for a human image video system, comprising the following steps: 1) acquiring a video image, and performing key point detection on each frame of the image; 2) performing attributive classification on each frame of the image according to the detected key points, and calculating confidence levels under various attributes; and 3) selecting P key frames according to the confidence levels of each frame of the image under different attributes as a basis of face recognition. Compared with the prior art, the process of selection for key frames is improved, so that the speed is ensured and higher recognition performances are achieved.
