主要通过matlab实现了数字水印方面的功能，比如，dct dwt

基于matlab的自适应仿真，其算法都是LMS算法，有系统辨识，噪声对消，自适应滤波器，陷波器，图像的DCT变换-adaptive emulation based on LMS,include system recognise,noise canceler,adaptive filter,dct transform

本程序是基于频域信息处理的压缩方法，把通过DCT图像转换到频域，最后还原成压缩图像。-The program is based on frequency domain information processing of the compression method, through the DCT image into the frequency domain, and finally reduction into compressed image.

基于matlab的数字图像水印系统，使用的是DCT算法-Matlab-based digital image watermarking system, using the DCT algorithm
