Instead of this:
thisImage=imread(files(k).myFolder);
where
- you did not include the folder when sending the filename to imread(), and
- you did not use the right variable (files instead of theFiles) and
- you did not have the right structure member off files (should be name, not myFolder),
try this:
fullFileName = fullfile(myFolder, theFiles(k).name);
thisImage=double(imread(fullFileName)); % Be sure to cast to double to prevent clipping.
