| 摘 要： | 提出一种基于曲波的彩色图像盲水印算法.该算法使用Arnold映射作为混沌系统,对水印图像做预处理,根据人眼的视觉特性,抽取人眼最不敏感的Q分量做曲波变换,并且对曲波的低频系数分块进行SVD分解,将水印以一定的深度嵌入到每个分块的最大奇异值上.实验证明,该算法透明性好,抗攻击能力强,是一种有效的图像鉴定算法.

| Abstract: | Based Curvelet,a blind watermarking of color digital image algorithm is given.The algorithm use Arnold chaotic system to scrambling watermarking image,and based HVS use Curvelet transformed initial image's Q component,blocked the low frequency component and SVD.The watermarking is embedded into the most SVD.The large amount of emulation experiment indicates that the algorithm is good blind watermark algorithm. |
