Abstract A key frames based method is proposed for recognition of complex human behavior. The body contours are adopted to represent actions. The complex behavior fragment is divided into simple behaviors by the shot boundary detection algorithm. To improve the recall rate, double sampling is employed during the segmentation. The self-splitting competitive learning algorithm is utilized to acquire key frames of simple behaviors. Finally, the recognition of complex human behavior is achieved according to the similarity of the key frames. During the process, the visual factor, the order factor and the interference factor are taken into account. Thus, the calculations of the recognition are more rational and comprehensive. The proposed method is verified on UCF Sports database and self-built database and the results indicate the high recognition accuracy of the proposed method.
