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

基于MATLAB的人脸识别算法，使用2D-DCT,自组织算法以及离散余弦变换-A MATLAB based Face Recognition System using Image Processing and Neural Networks

基于隐马尔科夫模型HMM的人脸识别程序，使用Matlab编写，提取的人脸识别特征为DCT系数-it is face detection codes based on HMM Model ，you can run iton Matlab，the feature from face is DCT
