摘 要:多媒体技术飞速发展,使得篡改软件具有了易获得、易操作的特点,其产生的伪造视频会严重扰乱社会秩序。为此,对篡改视频进行研究,针对对象移除视频,提出一种新的空时域联合检测算法。分别从时域、空域2个角度挖掘互补特征,以达到联合检测的目的。在时域提取残留信息时,从视频剖面图的角度分析篡改区域,不仅达到了降维的目的,还使得篡改痕迹更加明显。实验结果表明,该算法取得了较好的检测效果。With the rapid development of multimedia technology tampering software becomes more and more easy to be obtained and used. However,the subsequent forged video interfere the justice of judgment seriously in the meantime. So the detection of video forgery has become essential to enable the integrity of video data. In this paper,a spatial and temporal detection algorithm for detecting object deletion is proposed to mine residual information from the aspects of temporal domain and spatial domain respectively. At the first time,it obtains a good observation view by making use of the video profile to locate the video tampering region,when extracting residual information from temporal domain.Moreover,the algorithm can transforms the 3D video into 2D image effectively. Experimental results show that the proposed approach achieves excellent results on detection.
