You can also process the raw data to Yolo format via the tools shown here.

This repo is based on YOLOv5 repo. Please follow that repo for installation and preparation. The version I built for this project is YOLO v5 3.0. The proposed methods are also easy to be migrated into advanced YOLO versions.

1. Modify the config of the data in the data subfolders. Please refer to the instructions in the yaml file.

2. The command below can reproduce the corresponding results mentioned in the paper.

python train.py --img 640 --batch 12 --epochs 300 --data ./data/city_and_foggy8_3.yaml --cfg ./models/yolov5x.yaml --hyp ./data/hyp_aug/mm1.yaml --weights '' --name "test"

The codes have been released but need further construction. If you are intersted in more details of the ablation studies, you can refer to the folder "train_files_for_abl". I have listed nearly every train.py in this folder. I hope you find them helpful.

I will try my best to update :(. You can also check our previous work AcroFOD "https://github.com/Hlings/AcroFOD".
