Set union of Datastores with TransformedDatastores
Given an imageDatastore and some transformation of it, e.g., imds1 = imageDatastore({'street1.jpg','peppers.png'}); imds2 = transform(imds1,@(x) imwarp(x,tform)); I would like to form the set union of these data stores in some way so that trainNetwork processes the series of images from both imds1 and imds2 as a single combined set (and similarly with the response data). Is this possible in some way? I am aware that this functionality is somewhat captured by augmentedImageDatastore, but the operation I describe would open up a variety of data augmentation schemes not currently avaialble. I am also aware of this thread, https://www.mathworks.com/matlabcentral/answers/327026-how-to-join-or-merge-two-image-data-stores?s_tid=answers_rc1-2_p2_MLT but this does not cover what I am pursuing here, because the images in a TransformedDatastore are not physically stored anywhere (nor would I want them to be).
