一个自动添加高斯噪声 对比图像处理后psnr的程序 参数可自己修改-We want to test PSNR with variable gaussian blur. Then the different values of PSNR under different parameteres would be compared in order to find the relationship between PSNR and the gaussian blur.

图像的灰度直方图显示，二值图像显示的经典代码，还有psnr值计算-Image histogram display, binary image shows the classic code, there psnr value

图像量化，计算PSNR.图像量化，计算PSNR-calculate the PSNR of a picture
