Image denoising: Peak signal to Noise ratio calculation
This function used to calculate the peak signal to noise ratio for denoised image
function A = PSNR(G,H)
%G = original image
%H = denoised image
error = G - H;
decibels = 20*log10((255*255)/(sqrt(mean(mean(error.^2)))));
disp(sprintf('PSNR = %5.2f db',decibels))
A = decibels;
%G = original image
%H = denoised image
error = G - H;
decibels = 20*log10((255*255)/(sqrt(mean(mean(error.^2)))));
disp(sprintf('PSNR = %5.2f db',decibels))
A = decibels;
