Pretrained models

You can download pretrained DSLR model

• Trained with MIT-Adobe FiveK dataset

Note

1. you should place the weights in the ./data/model/
2. Dataset is also placed in the ./data directory (i.e., ./data/training_dataset)
3. Testset is placed in the ./data/test/input directory
4. test results are saved in the ./data/result/

Training

• DSLR: Deep Stacked Laplacian Restorer training

python main.py n
