【Special Effects】 Watermark_4 DL : 0: 信息隐藏与水印技术系列实验之四：DWT变换域不可见图像水印算法（开发工具：vc2005）：实现在一个256色灰度载体图像的DWT变换域低频LL系数中多次重复嵌入一个256色灰度文本图像水印。其主要功能如下：（1）可以载入不同的载体图像和水印图像，但载体图像和水印图像在本软件中被限制为256色灰度图像，若要用其它图像甚至彩色图像，请修改源码。（2）可以对含水印图像中的水印信息进行提取，提取时需要原始图像。（3）剪切攻击可使含水印图像中的水印信息部分丢失。（4）可以计算峰值信噪比（PSNR）和互相关系数（NC），以对含水印图像及提取水印进行客观质量评价。（5）源码结构清晰，在其基础上可快速开发出自己的水印软件。-err
