How to select images from nested folder?

3 views (last 30 days)
I have a folder named AAA. Inside folder AAA there is another folder name A, inside A there is another folder B. folder B consist of 300 images. I want to get every 10th number image from folder B ( It will be 30 images) and place these images in another folder C. I need a Matlab code for this Scenario. Any help?

Something like this should work. You will possibly need to add code to appropriately sort your list of images. I've marked where you would do it.
imageFolder = uigetdir('', 'Select Image Folder');
destinationFolder = uigetdir(imageFolder, 'Select Destination Folder');
contents = dir(imageFolder);
fileList = contents(~[contents.isdir]);
% Sort list as needed here
filesToMove = fileList(1:10:end);
fromPaths = fullfile(imageFolder,{});
toPaths = fullfile(destinationFolder,{});
for fileIdx = 1:numel(fromPaths)
copyfile(fromPaths{fileIdx}, toPaths{fileIdx})
Also I'm note sure the specific relevance of folders AAA and A. If AAA, A, and B are all known folders and you want to create C based on them, you could replace the uigetdir code with something like
imageFolder = fullfile(AAA,A,B);
destinationFolder = fullfile(AAA,A,C);
if ~exist(destinationFolder, 'dir')

Have you looked at imageDatastore()? Or dir() using two asterisks as the file pattern?
