摘要
在广播电视监视中应用的水印技术,由于在设计水印算法时多考虑了鲁棒性,而忽视了攻击者也在试图扰乱广播电视监视设备的正常工作(如伪造攻击),使其系统鉴别出虚假结果。这必将引发广播电视台与合法广告客户之间的重大纠纷。针对这种纠纷,提出了一种基于Prewitt算子的视频监控伪虚警鉴别方法。通过MATLAB的仿真实验,结果表明该方法具有很强的有效性和准确性。
Watermarking technology applied in radio and television surveillance is considered the robustness a little bit more when designing its algorithm but overlooked the attackers＇ attempts in trying to disrupt the regular operation of surveillance equipment of radio and television（such as forgery attack）,so that there are the false results to be identified by the system.This will inevitably lead to significant disputes between the radio and television companies and the legitimate advertisers.In view of such disputes,we propose a prewitt operator-based video surveillance identification method for pseudo-false alarm.Through MATLAB simulation experiment,the results show that this method has a strong validity and accuracy.
