| 摘 要： | 提出一种基于Radon变换的抗旋转和缩放攻击的零水印算法,检测时可利用Radon变换完成几何校正。该算法利用原始图像低频子图和置乱后水印图像得到提取矩阵,并生成密钥图像。提取时可根据密钥图像来提取水印,增强了水印的安全性。实验仿真结果表明,此方法有较强的鲁棒性,而且透明性很好。

| Abstract: | One method based on Radon transform,which is against scale and rotation attacks efficiently,is proposed.The secret image is obtained through the scrambled watermark and the low-frequency subcomponent of the original image.The watermark image can be extracted from the secret image.The experiment results show good transparency,robustness and security of this algorithm. |
