基于离散小波余弦变换DCT的数字水印算法，实现了水印的嵌入提取等过程。毕业设计源代码,Discrete Cosine Transform Based on Wavelet Digital Watermarking Algorithm in DCT, the watermark embedded in the realization of the process of extraction. Graduation Project source code

这是基于小波变换的数字水印代码,在嵌入的水印加上一个pn尾随机序列(This is a digital watermark based on wavelet transform code, plus a pn in the embedded watermark random sequence)

将要嵌入的多张水印图利用不同正交码调制，之后嵌入到被嵌入图片的小波变换系数中，对小波系数做逆变换，得到已嵌入水印图的图像。利用逆过程可提取出被嵌入的图像(The multiple watermark images to be embedded are modulated by different orthogonal codes, and then embedded into the wavelet coefficients of the embedded images, and the inv
