Description: 提出了一种基于小波域的图像数字水印算法·该算法将相互正交的两种水印(鲁棒水印和参考
水印)同时添加到经过DWT后的载体图像小波系数中,然后用小波反变换得到添加了水印的图像·用提取出
的参考水印来估计图像所受到的攻击,由于提取出的鲁棒水印所受的攻击与参考水印受到的攻击一样,因此
可以估计出原始的鲁棒水印·通过对嵌入水印的图像进行加入噪声、滤波、压缩以及裁剪等大量图像处理等试
验,均能正确检测出水印,表明该算法具有很好的感知效果和鲁棒性

Description: 一种基于多分辨率分解的图像水印嵌入方法
【摘 要】：根据小波变换的多分辨率的分析特征，提出了一种基于小波变换的水印嵌入方法，即在嵌入之前对水印做置乱处理，然后根据小波变换后的不同分辨率上的特点，将原始图像和水印进行小波分解，再将相同分辨率层次的数字水印分别嵌入其对应相同分辨率层次的原始图像中，使水印不可感知。试验结果表明，利用该方法较好的保持了图像的质量，并且对常用图像处理方法具有一定的健壮性，是一种行之有效的水印嵌入方法。-Based on multi-resolution decomposition of the image watermark embedding methods Abstract: Based on Wavelet Multi-resolution analysis of the characteristics of a wavelet-based watermark embedding method, that is, before the embedded watermark scrambling to do deal with, and then after the wavelet transform in accordance with a resolution on the different characteristics of the original image and watermark wavelet decomposition, and then the same resolution level of digital watermark embedding were the same as its corresponding original image resolution level so that the watermark can not be perceived. The experimental results show that the use of the method to maintain a good image quality, and commonly used image processing method has a certain degree of robustness, is an effective method of watermark embedding.
