I have one folder contain 50K images, I want to cut a group (5000 image) of this images according to indexing numbers. For example [ 6, 9, 2000,40215,...]. How to code such this?
path='E:\CIFAR-10\train';
jpeg_files = dir(fullfile(path,'*.png'));
for cnt = 1 : 50000
I{cnt} = imread(fullfile(path,jpeg_files(cnt).name));
% figure,imshow(I{cnt});
for j=1:5000
if cnt==class1num(1,j)
imwrite(I{cnt},sprintf('%s%d.jpg','0',cnt));
end
end
end
