See my answer here related to batch processing of csv files: https://www.mathworks.com/matlabcentral/answers/509790-read-and-manipulate-multiple-csv-files
Here is a general structure of the code
files = dir('*.jpg'); % get name of all files with jpg extension
for i=1:numel(files) % run the for loop over all images
    name = files(i).name; % get name of i-th image file
    img = imread(name); % load the image
    R=RGB(:,:,1); 
    % red surface image extraction
    G=RGB(:,:,2); 
    B=RGB(:,:,3);
    imwrite(R, ['img' num2str(i) ' red.jpg']);
    imwrite(G, ['img' num2str(i) ' green.jpg']);
    imwrite(B, ['img' num2str(i) ' blue.jpg']);
end
