Peak Signal-to-Noise Ratio

Peak signal-to-noise ratio (PSNR) shows the ratio between the maximum possible power of a signal and the power of the same image with noise. PSNR is usually expressed in logarithmic decibel scale. \( MSE =1/m*n \sum_{i=0}^{m-1} \sum_{j=0}^{n-1}  [   Image( i,j)  -NoisyImage( i,j)  ]  ^2   \) \( PSNR =10* \log_{10} \Bigg(MAXI^2/MSE\Bigg)  \) MSE is Mean Square Error and MAXI is […]
