MATLAB: How to pick files from sub-folder

MATLABsub-folder extractiontext file output

I have two sub-folders with images and require to perform operations using them. When i am running the code with sub-folder in the current folder window its being executed but i need to extract them from the main folder and run them. Also the ouput is a text file, which needs to be present in respective sub-folders instead of the current folder window. Please help me with these issues. Thank you in advance.

I recommend using dir to capture all the contents of your parent folder within a variable. Then you can use the contents of that variable to specify which child folder you want to work in.
folders = dir('parent folder path'); % Captures all contents of parent folder
folders = folders([folders(:).isdir]==1); % Filter to just folders
folders = folders(3:end);   % Remove unnecessary '.' and '..' directories
for i = 1:length(folders)
    path = [folders(i).folder,'\',folders(i).name];
    % do work with path variable directing to each child folder.
end
