Dependencies

This code uses the following libraries

• python 3.7+
• pytorch 1.1+ & tochvision
• scikit-image

Train and test on the adjusted ISTD dataset

Train

1. Set the path of the dataset in train_aistd_module1.py
2. Run train_aistd_module1.py
3. Set the paths of the saved module1 models (netG_A2B.pth,netG_B2A.pth) and the dataset in train_aistd.py
4. Run train_aistd.py

Test

1. Set the paths of the dataset and saved LG-ShadowNet models (netG_A2B.pth) in test_aistd.py
2. Run test_aistd.py

Evaluate

1. Set the paths of the shadow removal result and the dataset in evaluate.m
2. Run evaluate.m

Acknowledgments

Code is implemented based on Mask-ShadowGAN.

*Since the RMSE (MAE) in shadow and non-shadow regions are computed on each image first and then compute the average of all images, the results may be different from yours.
