基于视频指纹的快速视频拷贝检测方法

摘要

In order to meet the requirements of real-time video copy detection.a method of rapid video fingerprint schene is presented.The video fingerprint is generated by combining both the improved ordinal measure feature and the improved motion feature based on the DC image sequences.The qucry video streams can be identified by matching the candidate video.Experimental results show that the proposed video fingerprint has the advantage of higher discrimination and lower time complexity.%为满足视频拷贝检测的实时性要求,提出一种基于视频指纹的快速视频拷贝检测方法.基于DC图像序列提取改进的顺序度量特征和改进的运动特征,相结合生成视频指纹,通过视频指纹的相似性匹配对视频进行拷贝检测.实验结果证明,该方法能在保持准确性的同时快速地进行视频拷贝检测.
