Random crops enabled?

[vadimkantorov]

Hi @ycliu93!

Are random crops enabled as part of augmentation pipeline?

In other words, is cfg.INPUT.CROP.ENABLED set to True at

unbiased-teacher/ubteacher/data/dataset_mapper.py

Line 38 in ba543ed

if cfg.INPUT.CROP.ENABLED and is_train:

?

Right now it seems to me that it's disabled by default in detectron2 standard config and is not enabled anywhere else in unbiased-teacher

Thank you!

We didn't do randomly crop a patch from the whole image and use the cropped patch as input of the model.

Random cropping described in the paper is actually randomly masking patches in an image.

Setting cfg.INPUT.CROP.ENABLED to True might improve the performance but I didn't try before.

I see, so in fact RandomErasing is meant? Is it enabled? If yes, what are the hyper-params? Thank you!
