The invention relates to the technical field of video processing, in particular to a multi-video abstraction technology based on an archetypal analysis method with the weight. The technology is suitable for the characteristic, so that with the help of valid prior information, specific information of data is sufficiently used. According to the technical scheme, the multi-video abstraction method based on the archetypal analysis technology with the weight comprises the steps that firstly, the relation among graph model modeling video frames with weights is used, and accordingly a weight matrix which is required by archetypal analysis with the weight is acquired; then archetypal analysis with the weight is used for analyzing and acquiring key frames and generating video abstracts with the given length. The multi-video abstraction technology based on the archetypal analysis method with the weight is mainly applied to video processing occasions.
