For the traditional method to extract the surveillance video key frame, there are problems of redundant information, substandard representative content and other issues. A key frame extraction method based on motion target detection and image similarity is proposed in this paper. This method first uses the ViBe algorithm fusing the inter-frame difference method to divide the original video into several segments containing the moving object. Then, the global similarity of the video frame is obtained by using the peak signal to noise ratio, the local similarity is obtained through the SURF feature point, and the comprehensive similarity of the video image is obtained by weighted fusion of them. Finally, the key frames are extracted from the critical video sequence by adaptive selection threshold. The experimental results show that the method can effectively extract the video key frame, reduce the redundant information of the video data, and express the main content of the video concisely. Moreover, the complexity of the algorithm is not high, so it is suitable for the key frame extraction of the surveillance video.
