CoarseDropout throws NotImplementedError: Method apply_to_bbox is not implemented in class CoarseDropout

See original GitHub issue

🐛 Bug

To Reproduce

Steps to reproduce the behavior:

Add CoarseDropout augmentation to augmentation pipeline
Pass an image and bounding boxes to the augmentation pipeline

Expected behavior

CoarseDropout should not modify bounding boxes, as Cutout augmentation does

Environment

Albumentations version 0.5.2
Python version 3.7
OS Ubuntu 20.04
Albumentations installed viaconda

Any update on this?

I have implemented a partial solution which is:

if the box entirely masked by dropout it is removed
if only one side of box is affected by cutout mask, box is trimmed to reflect the actual non-masked area
we can also think to have an overlap-based threshold when the 90%+ of box is masked out while it’s bbox still remains the same and drop such instances as well

This should land as a PR in a next few days
