关于评价彩色图像质量的相关定义，如常用的MSE和PSNR，与灰度图像稍有区别，在图像的滤波、加密恢复等可以用得到。-Associated definitions on the evaluation of the color image quality, such as the commonly used MSE and PSNR slight difference with the grayscale image in the image filtering, encryption can be

PSNR CALCULATION The Mean Square Error (MSE) and the Peak Signal to Noise Ratio (PSNR) are the two error metrics used to compare image compression quality. The MSE represents the cumulative squared error between the compressed and the original image,
