| 摘 要： | 提出了一种基于奇异值分解（SVD）以及最小二乘法（LS）的变换域水印算法．该水印算法属于非盲水印，利用水印图像的部分信息替代载体图像的信息，增强了算法的鲁棒性．仿真结果表明，该算法不但可以对抗一般的图像处理，并且对缩放、裁剪、旋转等几何攻击有较强的鲁棒性．

| Abstract: | The paper proposes an image watermarking algorithm based on singular value decomposition （SVD） and least square method （LS） in transform- domain. It belongs to non - blind watermarking, and embeds the partial information of the watermark image. The simulation results show the algorithm not only is strong enough to resist common image processing, but also has good robustness on geometric attack such as zoom, image cut, rotate, and so on. |
