Peak Signal-to-Noise Ratio (PSNR) in Image using OpenCV and Matlab
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 […]
