Detailed Description

Optional data-augmentation transforms applied at training time.

All augmentations are disabled by default; set enabled to true and configure the per-transform fields to activate them. Each rotation / translation field defines a uniform sampling range whose lower bound is the *_minimum field and upper bound is the *_maximum field.
