本文针对同源视频的复制-粘贴篡改方式,提出了一种基于颜色特征的视频篡改检测方法,能够定位篡改位置并修复原视频。首先,计算各帧的颜色直方图,提取颜色特征并字典排序,计算邻近帧的帧间相似度获得匹配帧对;其次,针对全局颜色直方图不能表示颜色的空间分布信息,提取匹配帧对的彩色边缘特征进行复检;最后利用SIFT特征点的匹配精确定位篡改位置,并恢复原视频。实验表明,本文提供的方法在SULFA数据库视频检测上具有100%的准确率和召回率。
本文針對同源視頻的複製-粘貼篡改方式,提齣瞭一種基于顏色特徵的視頻篡改檢測方法,能夠定位篡改位置併脩複原視頻。首先,計算各幀的顏色直方圖,提取顏色特徵併字典排序,計算鄰近幀的幀間相似度穫得匹配幀對;其次,針對全跼顏色直方圖不能錶示顏色的空間分佈信息,提取匹配幀對的綵色邊緣特徵進行複檢;最後利用SIFT特徵點的匹配精確定位篡改位置,併恢複原視頻。實驗錶明,本文提供的方法在SULFA數據庫視頻檢測上具有100%的準確率和召迴率。

In view of the homologous video copy-move forgery, this paper proposes a video forgery detection way based on color features that can locate the forgery location and repair the original video. Firstly, calculating the color histogram of each frame, extracting color feature and sort in alphabetical order, computing similarity between neighboring frame for matching frame. Secondly, in view of the global color histogram unable to say the color spatial distribution of information, extracting the color edge feature of the matching frame and re-inspecting. Finally, using the SIFT feature points matching to accurately position the forgery location, and restoring the original video. The experimental results show that the provided method in the paper has 100%accuracy and recall rate on the video detection of SULFA database.
