*Memos:
My post explains RandomResizedCrop() about size argument.
My post explains RandomResizedCrop() about scale argument.
My post explains RandomResizedCrop() about ratio argument.
My post explains RandomResizedCrop() about size argument with scale=[0, 0] and ratio=[1, 1].
My post explains RandomResizedCrop() about scale argument with ratio=[1, 1].
My post explains OxfordIIITPet().
RandomResizedCrop() can crop a random part of an image, then resize it to a given size as shown below. *It's about ratio argument with scale=[0, 0]:
