hetong007 opened a new pull request #11027: Add standard ResNet data augmentation for ImageRecordIter
URL: https://github.com/apache/incubator-mxnet/pull/11027
 
 
   ## Description ##
   Add standard ResNet data augmentation for ImageRecordIter.
   
   Specifically, this augmentation performs a "random resized crop", which crop the image with respect to a random aspect ratio, and a random area, and resize it to the desired size.
   
   - If `random_resized_crop=True`, existing `max_random_scale` and `min_random_scale` will be ignored.
   - If `random_resized_crop=False`, newly-added `max_random_area` and `min_random_area` will be ignored.
