| 摘 要： | 提出了一种改进后的基于离散小波变换(DWT)和奇异值分解(SVD)的多重数字水印算法.本算法利用离散小波变换和奇异值分解技术在原始图像的四个子带中都分别嵌入两个数字水印图像.实验证明利用本算法嵌入的数字水印保证了数字水印的不可见性,并证明了用这种算法嵌入的数字水印对常见的攻击有很强的鲁棒性.

| Abstract: | There is an improved embedding algorithm for multiple digital watermarks based on DWT and SVD.Using the technology of DWT and SVD,two watermarks are embedded into four subbands of original image respectively.Experiment proves that the algorithm can assure good imperceptibility for watermarked image and the watermarks embedded using the algorithm have good robustness for familiar attacks. |
