lsb
- 用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，
DWT
- 代码利用DWT算法实现了电子水印技术。 其中包括了水印的插入，提取，以及4种不同的攻击。最后，测量了psnr-This algorithm describe digital watermark algorithm by using DWT. It implements embedding, extraction, and 4 different attacks. in the end, it measures psnr
