🌈We released a survey on deep learning-based low-light image enhancement------- Low-Light Image and Video Enhancement Using Deep Learning: A Survey, an online platform, a new dataset. Have fun! https://github.com/Li-Chongyi/Lighting-the-Darkness-in-the-Deep-Learning-Era-Open.

Pytorch implementation of Zero-DCE++

1. Python 3.7
2. Pytorch 1.0.0
3. opencv
4. torchvision 0.2.1
5. cuda 10.0

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

Or you can create a conda environment to run our code like this: conda create --name zerodce++_env opencv pytorch==1.0.0 torchvision==0.2.1 cuda100 python=3.7 -c pytorch

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

├── data
│   ├── test_data 
│   └── train_data 
├── lowlight_test.py # testing code
├── lowlight_train.py # training code
├── model.py # Zero-DEC++ network
├── dataloader.py
├── snapshots_Zero_DCE++
│   ├── Epoch99.pth #  A pre-trained snapshot (Epoch99.pth)

cd Zero-DCE++

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.

cd Zero-DCE++

python lowlight_train.py
