Image reconstruction based on statistical matching

Dependenices

• OS: Ubuntu 20.04
• nvidia :
  • cuda: 11.7
  • cudnn: 8.5.0
• python3
• pytorch >= 1.13.0
• Python packages: pip install -r requirements.txt

Training

The current config setting is for low-light enhancement but you can change the dataset path to adapt it for other tasks.

Run the training code:

cd codes/config/low-light
python train.py -opt=options/train/entropy-refusion.yml

Differentiable Spatial Entropy

Key code for the differentiable spatial entropy is the kde_utils.py.

Testing

Change the dataset and the pretrained model path in the option file.

cd codes/config/low-light
python test.py -opt=options/test/refusion.yml

Examples on the NTIRE challenge:

Pretrained models

We also provide the pretrained models for the challenge, LOLv1, and LOLv2-real.
