为了体现水印图像鲁棒性和不可见性的统一，在相同的水印质量条件下，对常规的图像处理和噪声干扰具有更好的鲁棒性。文章在研究小波变换、奇异值分解的基础上，提出了一种鲁棒自适应的水印算法，实验测试表明，此算法对JPEG有损压缩、中值滤波、亚抽样、低通滤波等各种的图像降级处理有很强的稳健性。

Based on block DWT decomposition and singular value decomposition, we proposed a new algorithm with the method of embedding the watermarking into the largest singular value. Meanwhile we produced a formula to estimate the PSNR. Experiments and attack test show that the algorithm has good robustness on JPEG, median filter, sub...
