| 摘 要： | 提出一种基于小波变换的数字图像水印算法．通过对宿主图像、经过Amold变换加密后的水印图像分别进行多分辨率小波分解，达到自适应嵌入水印信息的目的．实验采用在彩色宿主图像中分别嵌入灰度水印图像及彩色水印图像，表明该算法简便易实现，攻击实验表明该算法能够较好的保证图像质量并能经受一定的攻击，同时由于对原始水印图像进行加密处理，该算法达到了即隐藏信息的存在，又隐藏信息的内容的双重安全效果．

| Abstract: | A digital image watermarking algorithm based on wavelet transform is proposed.The multi-resolution wavelet decomposition of both the host image and the watermark image which is transformed and encrypted by Arnold for the self-adapting embedding process is finished.Experimentally a gray watermark image and a color one are embedded into the color host image,respectively.Experimental results show that the proprsed algorithm is easy to keep the qualiy of an image well,and can withstand varied attacks.Owing to encrypting the watermark image,the algorithm has had double safety effects,not only concealing information's existence but concealing its contents. |
