OutputSizeMode error in augmentedImageDatastore?

2 次查看(过去 30 天)
The images in my dataset are all 512x512 color images but when I process them with the following code:
imageSize=[299 299];
imageAugmenter = imageDataAugmenter('RandXReflection',true, 'RandXTranslation',[-100 100],'RandYTranslation',[-100 100],'RandRotation',[-5,5]);
augimdsTrain = augmentedImageDatastore(imageSize,imdsTrain,'DataAugmentation',imageAugmenter,'OutputSizeMode','centercrop');
augimdsValidation = augmentedImageDatastore(imageSize,imdsValidation,'OutputSizeMode','centercrop');
I get the error that the image size should be smaller then OutputSizeMode which is already true as the images are larger then [299 299]. Please assist me to guide where I am wrong.
When 'OutputSizeMode' in augmentedImageDatastore is 'centercrop', requested 'OutputSize' must be smaller than input image size.
