Wavelet_watermark
- VC实现数字水印的嵌入和提取算法 二值图像嵌入灰度图像的DCT变换系数中
数字水印源码
- 是关于数字水印的空域算法原代码，用的是delphi7.0。是把二值水印嵌入到原图像的低三位的嵌入算法-This is a watermark soucecode based on Spacial Domain Algorithm implemented by using Delphi7.0. The main idea is to embed the binary watermark into the primary image.

- 利用二维小波变换实现数字水印，首先在图像中加入水印，重构图像，分离水印，最后检测和计算阈值。-Two-dimensional wavelet transform digital watermark, the first to add a watermark in the image, the reconstructed image, separate watermarks, detection and calculation of the final threshold.
DCT
- 这段程序是，J（p，q）代表的二值水印图像，二值水印图像的像素值只有0和1，所以if J（p，q）==0，a=-1 ，是如果水印图像像素值是0的话，让a=-1，当水印像素值为1的话，让a=1，我个人认为是为了提取时候好提取-DCT digital watermark embedding and extraction of
