Intro

Night → Day (BDD100K)

Rainy night → Day (Alderdey)

Architecture

Our generator has asymmetric structure for editing day→night and night→day.
Please refer our paper for details

Envs

git clone https://github.com/jgkwak95/AU-GAN.git
cd AU-GAN

# Create virtual environment
conda create -y --name augan python=3.6.7
conda activate augan

conda install tensorflow-gpu==1.14.0   # Tensorflow 1.14
pip install --no-cache-dir -r requirements.txt

Preparing datasets

Night → Day
Berkeley DeepDrive dataset contains 100,000 high resolution images of the urban roads for autonomous driving.

Rainy night → Day
Alderley dataset consists of images of two domains,
rainy night and daytime. It was collected while driving the same route in each weather environment.

Please download datasets and then construct them following ForkGAN
