%% Randomly Split Labels % Create an |ImageDatastore| object and label each image according to the % name of the folder it is in. The resulting label names are |demos| and % |imagesci|. imds = imageDatastore(fullfile(matlabroot, 'toolbox', 'matlab', {'demos','imagesci'}),... 'LabelSource', 'foldernames', 'FileExtensions', {'.jpg', '.png', '.tif'}); imds.Labels %% % Create two new datastores from the files in |imds| by randomly drawing % from each label. The first datastore |imds1| contains one random file % with the |demos| label and one random file with the |imagesci| label. The % second datastore |imds2| contains the remaining files from each label. [imds1, imds2] = splitEachLabel(imds,1,'randomized')
