| 摘 要： | 提出了一种基于混沌置乱和JND阀值的小波水印新算法.采用二维混沌变换对水印图像加密,对载体图像进行离散小波变换,依据人眼的视觉系统特性,将两个水印信号正反嵌入到图像的中频部分.实验表明这种算法对常规的干扰具有良好的不可见性和鲁棒性.

| Abstract: | This paper proposes a new wavelet digital watermarking algorithm based on JND and chaotic scrambling.Two dimension chaotic transform is applied to encrypt watermarking image,and discrete wavelet is used to transform carrier image.Two watermarks are embedded in middle frequency part of image according to the character of human vision system.Experimental results show the algorithm is invisible and robust to certain common distortions. |
