Try this:
% Get a list of all TIFF files in the current folder AND in all subfolders below it.
fileListing = dir('**/*.tif*');
% For each file we learned of, process it...
numberOfFiles = length(fileListing)
for k = 1 : numberOfFiles
% Get the full filename (folder & base file name) of this particular file.
thisFullFileName = fullfile(fileListing(k).folder, fileListing(k).name);
fprintf('Processing image %d of %d : %s...\n', k, numberOfFiles, thisFullFileName);
% Now do something with this image. For example, display it:
% First read image into a variable.
thisImage = imread(thisFullFileName);
% Now display it.
imshow(thisImage);
drawnow; % Force immediate refresh of screen.
% Now perform other operations on the image if you want...
end
