**注意:** Faster R-CNN baseline仅使用 `2fc` head,而此处使用[`4conv1fc` head](https://arxiv.org/abs/1803.08494)(4层conv之间使用GN),并且FPN也使用GN,而对于Mask R-CNN是在mask head的4层conv之间也使用GN。 ## Citations ``` @inproceedings{wu2018group, title={Group Normalization}, author={Wu, Yuxin and He, Kaiming}, booktitle={Proceedings of the European Conference on Computer Vision (ECCV)}, year={2018} } ```
