CVPR2021(oral) [arxiv]
Requirements
- python3.7
- pytorch==1.5.0
- cuda10.2
Datasets
Cityscapes: Please follow the instructions in Cityscape to download the training set.
Dark-Zurich: Please follow the instructions in Dark-Zurich to download the training/val/test set.
Testing
If needed, please directly download the visualization results of our method for Dark-zurich-val and Dark-zurich-test.
To reproduce the reported results in our paper (on Dark-Zurich val), please follow these steps:
Step1: download the [trained models](https://www.dropbox.com/s/fmlq806p2wqf311/trained_models.zip?dl=0) and put it in the root.
Step2: change the data and model paths in configs/test_config.py
Step3: run "python evaluation.py"
Step4: run "python compute_iou.py"
If you want to evaluate your methods on the test set, please visit this challenge for more details.
Training
If you want to train your own models, please follow these steps:
Step1: download the [pre-trained models](https://www.dropbox.com/s/3n1212kxuv82uua/pretrained_models.zip?dl=0) and put it in the root.
Step2: change the data and model paths in configs/train_config.py
Step3: run "python train.py"
Acknowledgments
The code is based on AdaptSegNet, PSPNet, Deeplab-v2 and RefineNet.
