ST-CGAN: Stacked Conditional Generative Adversarial Networks for Jointly Learning Shadow Detection and Shadow Removal with PyTorch

This repository is unofficial implementation of Stacked Conditional Generative Adversarial Networks for Jointly Learning Shadow Detection and Shadow Removal [Wang+, CVPR 2018] with PyTorch.

Official Dataset and Code(coming soon...) is here.

Requirements

• Python3.x
• PyTorch 1.5.0
• pillow
• matplotlib

Usage

• Set datasets under ./dataset. You can Download datasets from here.

Then,

Training

python3 train.py

Testing

When Testing images from ISTD dataset.

python3 test.py -l <checkpoint number>

When you would like to test your own image.

python3 test.py -l <checkpoint number> -i <image_path> -o <out_path>

Results

Here is a result from test sets. (Left to right: input, ground truth, shadow removal, ground truth shadow, shadow detection)

Shadow Detection
