Augmented Image Datastore doesn't accept Image Datastore
显示 更早的评论
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);

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

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".

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