| 摘 要： | 提出一种Wavelet和SVD结合的水印算法，首先对原图像和置乱的水印图像分别进行两次相同的Wavelet变换，对他们的低频均进行奇异值分解，通过奇异值加权得到含水印图像，实验表明，此算法对常规的攻击具有很好的鲁棒性。

| Abstract: | The watermarking algorithm is proposed based on Wavelet-SVD.Fish the thesis introduces that the watcrmark image and the scrambled watermark is conducted the same wavelet transformation. The low-frequency is conducted SVD. The embeded image is got hy the singalar value weighted. The experiments show that this algorithm has better robust against lhe common attatcks. |
