how to import multiple folders containing images ,in matlab?

Question

I want to select just folders instead of selecting each images individually. for example I have 8 folders and each of then including 72 dicom images. my purpose is to just select 8 folders and save each folder images in one row of array. I have written this code but it only read multiple images in one folder. please help me to solve my problem.

function cell=readfromfile()
[filename, pathname] = uigetfile('*.*', 'Pick folder','Multiselect','on');
img_dir =pathname;
filename(1);
    N =length(filename);
strfile =filename{1};
img = dicomread(fullfile(img_dir, strfile));
siz_img = size(img);
% create result matrix:
% load all the remaining images and put them in the matrix
for ii=2:N
    strfile =filename{ii};
    I{ii}=dicomread( fullfile(pathname, filename{ii}) );
end

Neither uigetfile or uigetdir allow you to select multiple folders, so I would probably just use uigetdir to get the path of the selected folder. If you know you have 8 folders you can just call this in a loop 8 times (making sure not to overwrite you data). If you don't know how many folders you have you may need to so something cunning, but I haven't really thought about it.

I would then use dir to get a list of the files in your folders. You may need to use something like dir('*.png'); if you have any subfolders or other files you don't want to read in the folder.

Your reading of the images looks fine from there.
