改程序实现了数字水印的功能，很好的代码，对学习数字水印的同仁很有帮助。-It is a good codes to acheive the watermark!

可采用一段伪随机序列来控制水印嵌入位置,matlab代码-It may be a period of pseudo-random sequences to control the watermark embedding position, matlab codes

codes in mat lab for watermark generation and embedding

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
