Hi,

As per my understanding, you have a dataset of images and a separate labels file and want to couple the labels with the images so as to split the dataset into training and test set.

After creating the Image Datastore ‘imds’, the labels for the files can be set using the ‘Labels’ property of the datastore as follows,

imds.Labels = label

This would link the labels to the images in the datastore. The ‘label’ for the files can be specified as a vector, a cell array or a string array.

For more information, please refer to the Image datastore documentation: https://in.mathworks.com/help/matlab/ref/matlab.io.datastore.imagedatastore.html
