## 基于DWT和DCT的鲁棒图像水印系统

#### 本项目实现的功能

- 预处理算法

- Arnold置乱算法

- Logistics混沌序列算法

- DWT加密及解密算法

- DCT加密及解密算法

- 抗鲁棒攻击系统

- 嵌入提取界面

- 抗鲁棒攻击界面

- 评价指标 PSNR,NC 评价算法的鲁棒性

#### 项目介绍

1. 利用 Logistic 算法对二进制水印进行加密，产生的混沌序列具有较好的不确定性和初值敏感性。
2. 对加密后的水印图像进行 Arnold 变换，消除水印像素之间的相关性，从而提高图像信息的鲁棒性。
3. 在嵌入过程中，对原始图像进行二级小波分解，然后对低频子带 LL1 进行分块，增强水印的鲁棒性。
4. 通过 DCT 变换修改中频系数，嵌入预处理后的水印信息，兼顾了鲁棒性和不可见性。
5. 该算法进行了抗鲁棒攻击仿真实验，在受到各种恶意攻击时具有良好的隐蔽性和鲁棒性。
6. 本项目编写了水印系统界面，GUI为本算法提取嵌入水印的界面，包括 Logistic 混沌序列加密、Arnold 变换、融合DWT及DCT的嵌入与提取算法。GUI1为本算法遭到五种攻击后提取水印的界面，其中包括滤波攻击、噪声攻击、缩放攻击、旋转攻击、剪切攻击。其中滤波攻击后提取效果过于良好，因此未在项目中展示，而使用0.05噪声攻击替代之。
