本程序主要用两种方法对前后输入两幅RGB图像计算处理，分别计算了其均方差MSE和峰值信噪比PSNR；方法1:如果读入图像为彩色图象, 首先进行灰度化处理,依照灰度图象计算 方法2:对RGB图像均方差是所有方差之和除以图像尺寸再除以3 -This program before and after the input of two ways two RGB image calculation process to calculate the mean square error MSE an

采用全逆滤波和最小均方误差（维纳）滤波对退化的图像进行还原.图像复原技术就是将图像退化过程模型化，并且采用相反的过程进行处理，以便复原出原始图像.-The full inverse filtering and minimum mean square error (Wiener) filter to restore the degraded image image restoration technology is the process of image degradation model, a

以下在matlab中利用图像处理工具箱实现均方误差（MSE）、峰值信噪比（PSNR）和熵的源代码 -The following use in matlab image processing toolbox mean square error (MSE), the peak signal to noise ratio (PSNR), and entropy source code
