摘要
提出基于图的视频拷贝检测方法,该方法将视频序列匹配结果转换为匹配结果图,进而将视频拷贝检测转换成在匹配结果图中查找最长路径的问题。实验结果显示基于图的序列匹配算法拷贝定位准确度高,可弥补图像底层特征描述力不足的缺陷,节约检测时间,批量定位2段视频序列中可能存在的多段拷贝。
This paper proposes an efficient graph-based approach for video copy detection. It converts the video sequence matching results to a matching results graph, so the problem of video copy detection becomes a problem of finding the longest path in the matching results graph. Experimental results show that the graph-based video sequence matching algorithm has many advantages, such as high copy locating accuracy, making up for inadcquate description of image low-level features, saving detecting time, batch detecting the more than one copy which exist in two video sequences and so on.
