MATLAB: Image resizing using augmentedImageDatastore

resize

i tried to resize the image stored in the following path. C:\Users\manjurama\Desktop\study\PG\PROJECT\finger vein database\database_10
imagefolder = 'C:\Users\manjurama\Desktop\study\PG\PROJECT\finger vein database\database_10';
imds = imageDatastore(imagefolder,'IncludeSubfolders',true,'LabelSource','foldernames');
veinimage = augmentedImageDatastore([227 227],imds)
numTrainFiles = 0.75;
[TrainImages, TestImages] = splitEachLabel(veinimage, numTrainFiles,'randomize'); % this is the line 14 error shown here.
But i got this error
Check for missing argument or incorrect argument data type in call to function 'splitEachLabel'.
Error in Classification (line 14)
[TrainImages, TestImages] = splitEachLabel(veinimage, numTrainFiles,'randomize');
Could you please let me know about the problem in my code. Thanks.

Hi Rd,
I had same problem and fixed by splitting the data before I do the augmentedImageDatastore then have two augmentedImageDatastores one for the training portion and one for testing. So the code will be like.
imagefolder = 'C:\Users\manjurama\Desktop\study\PG\PROJECT\finger vein database\database_10';
imds = imageDatastore(imagefolder,'IncludeSubfolders',true,'LabelSource','foldernames');
numTrainFiles = 0.75;
imageSize = [227 227];
[TrainImages, TestImages] = splitEachLabel(imds, numTrainFiles,'randomize');
TrainImages = augmentedImageDatastore(imageSize,TrainImages)
TestImages = augmentedImageDatastore(imageSize,TestImages)
