How to measure quality of an image?
I need to find quality of an image before and after pre-processing. For this, i need to calculate PSNR (Peak Signal to Noise Ratio), MSE (Mean Square Error),MAXERR (Maximum Squared Error) and L2RAT (Ratio of Squared Norms) X = imread('africasculpt.jpg');
Xapp = X;
Xapp(X<=100) = 1;
[psnr,mse,maxerr,L2rat] = measerr (X,Xapp)
figure;
subplot(1,2,1); image(X); 
subplot(1,2,2); image(Xapp)…
