摘要: 为了达到版权保护的目的,提出一种Contourlet变换与生命游戏置乱相结合的视频零水印,Contourlet被誉为处理二维信号的最优解,算法利用其优势对关键帧处理得到低频系数,再经过核心算法处理,最后结合生命游戏规则生成特征图像,并运用加密算法对水印进行预处理以加强安全性。实验结果表明本算法较好地折中了数字水印的不可见性和鲁棒性,并能有效地抵抗常见的几何攻击和视频攻击。

Abstract: In order to achieve the purpose of copyright protection, this paper proposes a video zerowatermark algorithm based on the combination of the life game scrambling with Contourlet transform, which has been known as the optimal solution of twodimensional signal processing. The algorithm uses the advantage of Contourlet to process the key frame and gets the lowfrequency coefficients, then combines the rules of the life game to generate feature image with core algorithm, and uses encryption algorithm to make pretreatment for watermark in order to enhance security. Experimental results show that the algorithm is a good compromise between invisibility and robustness, and can effectively resist the common geometric attacks and video attacks.
