这个是用matlab编写的对图像嵌入数字水印的程序，基于dct变换，实现对图像的dct算法的数字水印程序-this is the right preparation Matlab embedded digital watermark image of the procedure, based on the A1501 transform, achieving the right image A1501 digital watermarking algorithm procedures

用matlab实现的有一个数字水印程序，它也是基于dct算法的数字水印程序，对一副图像进行dct变换然后嵌入水印-using Matlab is a realization of the digital watermarking procedure, which is based on the A1501 digital watermarking algorithm procedures, a pair of images Extra Transform then embedded waterm
