Hi, I'm using this user-defined function (exrread) to read .exr file but how can I read all of my .exr files at once? I try to use dir and put .* after the name of the file but I still couldn't get the list of all my files. k=exrread('file.exr'); This k value will be used to calculate MSE.

在 MATLAB Online 中打开

dinfo = dir('*.exr');
nfile = length(dinfo);
for K = 1 : nfile
  thisfile = dinfo(K).name;
  try
    data = exrread(thisfile);
    fprintf('Was able to read file "%s"\n', thisfile);
  catch
    fprintf('Was not able to read file "%s"\n', thisfile);
  end
end

I have 94 compressed images to be compared to their respective original images.

Are the compressed files and the original files in different directories? Given the name of a compressed file, how can you determine the name of the original file (or the other way around) ?
