Augmented Image Datastore doesn't accept Image Datastore

I have been using imageDatastore for training networks. All works fine.

Next, I wanted to create augmentedImageDatastore.

The documentation explains that imageDatastore can be used. https://uk.mathworks.com/help/nnet/ref/augmentedimagedatastore.html

however when try to do it, I receive this error

Undefined function 'augmentedImageDatastore' for input arguments of type 'matlab.io.datastore.ImageDatastore'

% all my images are 50x50x3
imageSize = [50 50 3];
augimds = augmentedImageDatastore(imageSize,imds);

I think this maybe something with the ReadFcn but it is default: @readDatastoreImage Is this possible to use imageDatastore, how if yes? I am using Matlab 2017b Thanks

I think that is only possible in 2018a as I have no problem in the 2018 version but it does not work in 2017b. You should be able to use the following function instead (which is to be removed in future versions);

 augimds = augmentedImageSource(imageSize,imds);

thanks, that was it.

You tagged with Computer Vision product but it is part of the Neural Network product.

Hi, Thanks. The tag has been added automatically I guess, I just typed Matlab. Anyway, I cannot change the tagging and not sure how i can use this answer. If you know the real answer, please can you share? Thanks

imageDatastore() is in the Computer Vision System Toolbox. Maybe it's included in both toolboxes. I'm adding the Deep Learning toolbox to the Product List. The Neural Network toolbox is gone from the list right now. It was gone before and replaced by Deep Learning, but then they put it back, but now it's gone again replaced by the Deep Learning Toolbox again. I think there is some kind of gradual, on-again-off-again attempt at the Mathworks to rename the Neural Network Toolbox as "Deep Learning Toolbox".

[Walter Roberson]

I suspect you do not have the Neural Network Toolbox installed.

hi Walter, I have had all toolboxes including neural nets and have been using it. This was the problem of 2017 version. thanks anyway for kindly replying Greg
