Secondly algorithms for the detection of the video shot boundaries with complex editing and the discrimination of camera motion and gradual transition are presented .

提出了一种能够适应复杂镜头边界编辑效果的 视频镜头分割算法和一种能够有效地区 分镜头运动与渐变的方法。

We extract video fingerprint based on the improved SIFT . The video fingerprint extracted by the improved SIFT has the characteristics of higher discrimination stronger robustness and lower time complexity of video fingerprint extraction .

我们对SIFT方法进行改进提取视频指纹，改进后的SIFT视频指纹区 分度更高、鲁棒性更强，并且 视频指纹提取时间复杂度较低。
