82,
83].
| Models | Training dataset | Voting strategy | mAP (of rain and fog) (in %) |
| Previous models (mAP is for all 4 categories) | Faster R-CNN with several RPNs (with Faster R-CNN backbone) [84] | DAWN | n/a | 89.48 |
| Previous models | Standard data augmentation [82] | Pretrained on ImageNet and fine-tuned on the” clear” split of BDD100k-cls | n/a | 23.3 | AMDA [82] | Pretrained on ImageNet and fine-tuned on the” clear” split of BDD100k-cls | n/a | 25.55 | Ensemble (AMDA, AMDA) [82] | Pretrained on ImageNet and fine-tuned on the” clear” split of BDD100k-cls | n/a | 25.8 | RoHL (AMDATV-ftGauss, AMDA-ftCont) [82] | Pretrained on ImageNet and fine-tuned on the HF and LF biases. | n/a | 24.9 |
| Proposed models | RetinaResnet50 | COCO | Affirmative | 32.75 |
