计算两幅图像的相似度，与psnr有所区别，根据两幅图像的纹理结构来判断两幅图像的相似度-Calculate the similarity of two images, and psnr be different, according to the texture structure of the two images to determine the similarity of two images

可以计算图片在处理前后的峰值信噪比峰值信噪比-compute pnsr

计算bd-psnr的一个小软件，比较实用，研究视频时，一定会用到的-Calculation bd-psnr a small software, more practical, research video, certainly will use

计算图像的均方误差和峰值信噪比，来评价图像的质量-MSE is calculated images and peak signal to noise ratio, to evaluate the quality of the image
