How to implement image preprocessing using imageDatastore?

8 views (last 30 days)
I want to do image preprocessing before implementing deep lerning, MATLAB dosn't accept "transformed imageDatastor":
imds: imageDatastore
imds_T = transform(imds,@(x) medfilt2(x)); %imds_T: transformed imageDatastor
I tried to apply "splitEachLabel" and I got the following error:
Undefined function 'splitEachLabel' for input arguments of type 'matlab.io.datastore.TransformedDatastore'.
What is the problem?

Perhaps you can use splitEachLabel to separate your training and test datasets first, before you apply the transform.
