| description | The invention relates to a video key frame self-adaptive extraction method under emotion encourage. The video key frame self-adaptive extraction method comprises the steps of: thinking in terms of emotional fluctuation of a video looker, computing exercise intensity of video frames to serve as visual emotion incentive degrees of the video looker when looking a video, computing short-time average energy and tone as audition emotion incentive degrees, and linearly fusing the visual emotion incentive degree and the audition emotion incentive degree to obtain the video emotion incentive degree of each video frame and then generate a video emotion incentive degree curve of the scene; obtaining video key frame number KN shall be distributed to the scene according to the video emotion incentive change of the scene; at last taking the video frames corresponding to KN crests before the highest emotion incentive degree of the video emotion incentive degree curve as the scene key frames.
