| 摘 要： | 结合视频压缩标准、脆弱数字水印及视频通信技术,文中提出一种有效识别正版视频的TDIA算法.它包括嵌入算法和识别算法两部分.为消除通信干扰对水印的影响,将迭代方法引入识别算法.基于盗版操作与通信干扰的本质不同,研究讨论了迭代方法的性能.最后,基于迭代结果,借助Chernoff Bound理论,分析了TDIA算法的识别误差.对于码流BER(Bit Error Rate)10-3、视频I帧总数n360的Mpeg2编码视频,该算法识别误差小于10-18.

| Abstract: | An efficient genuine-video identification algorithm named as TDIA is proposed,which based on integration of video compression standards,fragile watermarking and video communication technology.It includes two parts:embedding algorithm and identification algorithm.Iterative method is introduced on the identification algorithms to eliminate the communications interference for the impact of watermarking.The performance of the iterative method is investigated according to the difference of nature between piracy ... |
