I provided a code that gets an initial image as input and gives me 4 images as result. I should run this code as loop that user enters an initial images. in this loop every time I should save all the results because I want to make a dataset of these images and then do feature extraction. how can I do this? Can I use structure for this? I think that we can imagine every image as a matrix but I don't how we can do this .I think I should have a dataset of images like this:
but I dont know how can make you think this idea is rational?or I should change my approach.
I appreciate your helps and supports in advanced.

A struct is fine.
datastruct = struct('IMG1', [], 'IMG2', [], 'IMG3', [], 'IMG4', []);
while true
[filename, pathstr] = uigetfile('Select an image');
if ~ischar(filename) %user canceled
fullname = fullfile(pathstr, filename); %it might not be in current directory
... process file named by fullname
datastruct(end+1).IMG1 = image1;
datastruct(end).IMG2 = image2;
datastruct(end).IMG3 = image3;
datastruct(end).IMG4 = image4;

Why can't you do feature extraction immediately after you create them, and not worry about saving these intermediate images? Why do you have to save them all? If, for some reason you do, then I'd just save them in .mat files until you need them at some later time.

Please create a new Question for that topic; it has nothing to do with this Question.
