Shadow detection results at test datasets

The results of shadow detection(w & w/o crf) on three datasets (SBU, UCF, ISTD) can be found at Google Drive or BaiduNetdisk(password:131b for BaiduNetdisk).

Trained Model

You can download the trained model which is reported in our paper at BaiduNetdisk(password: h52i) or Google Drive.

Requirement

• Python 3.6
• PyTorch 1.3.1(After 0.4.0 would be ok)
• torchvision
• numpy
• tqdm
• PIL
• pydensecrf (here to install)
