ref = imread('pout.tif'); A = imnoise(ref,'salt & pepper', 0.02);
[peaksnr, snr] = psnr(A, ref);
fprintf('\n The Peak-SNR value is %0.4f', peaksnr); fprintf('\n The SNR value is %0.4f \n', snr);

HI Tina There is no inbuilt function for psnr, we want to implement with the eqaution and the datatype of the two image in the psnr should be same as double or uint8..
if one is in uint8 and another is in double means it will not work
