Dataset Preparation

You can download NTIRE 2021 NonHomogeneous Dehazing Challenge dataset after participating the challenge in the following link: https://competitions.codalab.org/competitions/28032

Your dataset directory should be composed of three directories as following:

dataset_directory
|-- train
|   |-- HAZY
|   |   |-- 01
|   |   |-- 02
|   |   `-- ...
|   `-- GT
|       |-- 01
|       |-- 02
|       `-- ...
|-- val
|   |-- HAZY
|   |   `-- ...
|   `-- GT
|       `-- ...
`-- test
    `-- HAZY
        `-- ...

Train

You can start training your model by following command:

$ python main.py train
Additional arguments:
    --data-dir: Dataset directory
    --gpus: Invidual GPU number(s) to use(e.g. 0,1,2)
    --name: Name of the experiment
    --batch-size: Training batch size
    --epochs: The number of total epochs
    --lr: Initial learning rate
    --lr-mode: Learning rate scheduling mode
    --step: Step size for learning rate decay
    --weight-decay: Weight decay factor
    --crop-size: Random crop size for data augmentation
    --random-scale: Random scaling ratio for data augmentation
    --random-rotate: Random rotating degree for data augmentation
    --random-identity-mapping: Random identity mapping ratio for data augmentation

Test

You can test your pretrained model by following command:

$ python main.py test -d [data path] --resume [pretrained model path] --phase test --batch-size 1
