%X 近年来，随着数字媒体软件的火热，网络中的近重复相似视频呈爆炸似增长，因此快速准确地筛选出海量视频中的同源视频是当下研究的重点课题。针对该课题，本文采取了基于帧间特征矩阵的同源视频检测方案，首先在视频帧间时空关系矩阵的基础上确定视频相应类别，然后进一步通过视频帧间特征序列对比来确认所检测视频是否与该类下的其他视频存在重复片段，并定位重复片段在视频中的位置。当重复片段占比超过一定阈值，即可判定被检测视频为同源视频。实验表明该方法在CC_WEB数据集上平均准确率可达93.2%，由此证明了该方法在保护视频知识产权领域的可用性。<br />
In recent years, with the popularity of digital media software, the nearly repeated similar videos in the network are exploding. Therefore, it is a key topic of current research to quickly and accurately screen out the homologous videos in the massive videos. For the subject, this paper adopted homologous video detection scheme based on characteristic matrix between frames. First, the corresponding categories of the video are determined on the basis of the space-time relationship matrix between the video frames, and then through the characteristics of sequence comparison between video frames to confirm whether the detected video has duplicate segments with other videos under this category, and locate the position of duplicate segments in the video. When the proportion of repeated clips exceeds a certain threshold, the detected video can be judged as homologous video. Experimental results show that the MAP (Mean Average Precision) of this method can reach 93.2% on CC_WEB data set, which proves the applicability of this method in the field of video intellectual property protection.
