How can I measure PSNR or MSE for 100 images and save the result to excel file? I can do it for one image each time but it take so long to finish the 100 images.

在 MATLAB Online 中打开

 % Example code
list = dir('*.jpg') %list of images in the directory
for i = 1:length(list)
      I = imread(list(i).name);
      A = imnoise(I,'salt & pepper', 0.02);
      [peaksnr, snr] = psnr(A, I);
      MSE=mean2((A-I).^2);
      data(i,:) = [peaksnr MSE];
end
 xlswrite('mmse.xlsx',data);
