Hi,

if you take a look at TestFiles(1).name you will see the ".", which is the current folder. Several possibilities: if you e.g. only have files with .jpg, you could write

TestFiles = dir(fullfile(FullPath, '*.jpg'));

or similar for other file formats. If you need all image files, be sure to not read "." and ".." by e.g.

if ~strcmp(TestFiles(i).name, '.') && ~strcmp(TestFiles(i).name, '..')
  S = imread(...);
end
