how to read image from folder with many subfolder directories

I need to read images from many subfolders in a fixed folder for further processing of image in a loop.

For better understaning a flowchart is given here.

My matlab code and datasetImage folder are in same folder.I need to read image .tif image in every subfolders.For note there are some folders which is missing like IM005.It will be very helpfull if anyone can help me to read ***.TIF file for further processing.Thanks in advance.

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

It doesn't matter if some files or folders are "missing" - the fileListing will contain a list of only those files that are there and process only those. You can put your feature extraction below the line of code that says "Now perform other operations...".

Try something like this

files = dir('**/*.tiff');

for i=1:numel(files)
    filename = fullfile(files(i).folder, files(i).name);
    
    % do preocessing on images. for example:
    im = imread(filename);
    % more code
end

I was having problem to understand this.It will be very hepfull for me if you can write it in more detail.

[Ameer Hamza]

Can you tell what are you trying to do with each figure file or show some code? I can give a more specific answer only after that.

[riya shahrin]

I want to process the images for some feature extraction like colour presense and classify it.

I was facing problem as in dataset some folder are missing(e.g in figure IM005 folder is missing) and some of some subfolders are not using(e.g in figure IM002_LS subfolder is not using).

[Ameer Hamza]

The code will read the name of all the files and load them inside the for loop one by one. The images are loaded in the variable im. You can then apply the feature extraction function using im as input.
