| 摘 要： | 提出了一种基于多小波变换和分块SVD的非盲水印算法。选择彩色图像的饱和度分量作为水印的嵌入域,水印为有意义的灰度图像,水印经Arnold置乱后被嵌入到饱和度分量多小波变换的不同中频区域中。实验证明,该算法不仅对噪声、JPEG压缩、剪切及Photoshop处理具有很好的鲁棒性,而且能抵抗旋转、放缩和平移等几何攻击。

| Abstract: | A non-blind watermarking algorithm is proposed based on multi-wavelet transform and block singular value decomposition.Choosing the saturation component of a color image as the watermark embedding domain,the watermark is a meaningful grayscale image.After Arnold scrambling,watermark is embedded into the different mid-frequency regions of the saturation component which through multi-wavelet transform.The examples demonstrate that the algorithm not only has good robustness to the noise,JPEG compression,shear ... |
