- 由于二维DCT变换是对数字图像矩阵而言的，所以对于RGB位图不能进行DCT变换我在这里先将它转换成灰度图像再把水印嵌入到灰度图像中来进行基于DCT变换的图像水印研究。-As the two-dimensional DCT transform on the digital image matrix is concerned, therefore, for the RGB bitmap should not be DCT Transform I first convert it into gray

Digital-watermarking-
- 以数字图像为载体，将水印信息嵌入到图像的DCT系数中，然后对加入数字图像中的水印进行提取。-In the digital image as the carrier, the watermark information is embedded into the image DCT coefficients, and then add digital watermark image extraction.
