Zero-Reference Deep Curve Estimation for Low-Light Image Enhancement

We relese our testing code first. The Zero-DCE is in the product, so we may release the training codes late.

You can find more details here: https://li-chongyi.github.io/Proj_Zero-DCE.html. Have fun!

The implementation of Zero-DCE is for non-commercial use only.

Pytorch

Pytorch implementation of Zero-DCE

Requirements

1. Python 3
2. Pytorch

Zero-DCE does not need special configurations. Just basic environment.

Folder structure

Download the Zero-DCE_code first. The following shows the basic folder structure.

├── data
│   ├── test_data # testing data. You can make a new folder for your testing data, like LIME, MEF, and NPE.
│   │   ├── LIME 
│   │   └── MEF
│   │   └── NPE
│   └── train_data # will release soon
├── lowlight_test.py # testing code
├── model.py # Zero-DEC network
├── dataloader.py
├── snapshots
│   ├── Epoch99.pth #  A pre-trained snapshot (Epoch99.pth)

Test

python lowlight_test.py 

The script will process the images in the sub-folders of "test_data" folder and make a new folder "result" in the "data". You can find the enhanced images in the "result" folder.
