Select folders one by one using imageDatastore function

4 views (last 30 days)
Dear all,
I have a "Parent_Folder" and inside it I have another 5-subfolders that contain images inside them: Folder_1, Folder_2, Folder_3, Folder_4, Folder_5.
By using "imageDatastore" function, I want to make a loop in order to chose folders one by one, something like this:
for i = 1: 5
%in the 1st loop when i = 1
Group_A = Folder_1
Group_B = Folder_2, Folder_3, Folder_4, Folder_5
%in the 2nd loop when i = 2
Group_A = Folder_2
Group_B = Folder_1, Folder_3, Folder_4, Folder_5
%in the 3rd loop when i = 3
Group_A = Folder_3
Group_B = Folder_1, Folder_2, Folder_4, Folder_5
and so on.
Any idea how to make such a loop?
best regards,
Mesho

Hello,
I understand that you have a "Parent_Folder" and want to have five sets of "Group_A" and "Group_B" subfolder groups such that "Group_A" has one subfolder and "Group_B" has the rest of the four folders to store the images inside them in a "imageDatastore" with the help of their paths.
Please refer to the below code snippet that illustrates this task:
parentFolderPath = 'Parent_Folder';
subfolders = {'Folder_1', 'Folder_2', 'Folder_3', 'Folder_4', 'Folder_5'}; % List of subfolder names
for i = 1:length(subfolders)
% Group_A will be the current subfolder
groupAPath = fullfile(parentFolderPath, subfolders{i});
Group_A = imageDatastore(groupAPath, 'IncludeSubfolders', true, 'LabelSource', 'foldernames');
% Group_B will be all other subfolders
groupBPaths = subfolders([1:i-1, i+1:end]); % Exclude current folder
groupBPaths = fullfile(parentFolderPath, groupBPaths); % Full paths
Group_B = imageDatastore(groupBPaths, 'IncludeSubfolders', true, 'LabelSource', 'foldernames');
end

Hope it helps!
