| 摘 要： | 针对DCT域的最优均值量化盲水印算法抵抗剪切、旋转、缩放等几何攻击的能力不强,给出了一种DCT-SVD图像水印算法.该算法利用奇异值具有几何不变性,使算法具有较好抗几何攻击性能.实验结果表明,该算法对加噪、JPEG压缩、滤波、几何攻击等多种攻击都具有很强的鲁棒性.

| Abstract: | A DCT-SVD image watermarking algorithm is proposed,this algorithm uses singular value with the characteristic of geometrical invariability with better resistance to geometric attack. Experiment results show that the algorithm is robust against lots of attacks such as noise adding,JPEG compression,filtering and geometrical attacks. |
