This MATLAB code is an example of how to train the GCRF model described in \"Learning Gaussian Conditional Random Fields for Low-Level Vision\" by M.F. Tappen, C. Liu, E.H. Adelson, and W.T. Freeman in CVPR 2007. If you use this code in your re

matlab对图像随机添加四种噪声，然后分别通过自编中值滤波，均值滤波，高斯滤波，和维纳滤波进行滤波-matlab add four random noise to the image, and then were filtered by self median filtering, mean filtering, Gaussian filtering, and Wiener filtering

以matlab实现数字水印的生成和提取,用的是高斯随机序列-With matlab the generation and extraction of digital watermarking, using a gaussian random sequences
