# Strong Baselines

<!-- [OTHERS] -->

We train Mask R-CNN with large-scale jitter and longer schedule as strong baselines.
The modifications follow those in [Detectron2](https://github.com/facebookresearch/detectron2/tree/master/configs/new_baselines).

## Notice

When using large-scale jittering, there are sometimes empty proposals in the box and mask heads during training.
This requires MMSyncBN that allows empty tensors. Therefore, please use mmcv-full>=1.3.14 to train models supported in this directory.
