Representitive Results

Overal Architecture

Environment Preparing

python3.5

You should prepare at least 3 1080ti gpus or change the batch size.

pip install -r requirement.txt </br> mkdir model </br> Download VGG pretrained model from [Google Drive 1], and then put it into the directory model.

Training process

Before starting training process, you should launch the visdom.server for visualizing.

nohup python -m visdom.server -port=8097

then run the following command

python scripts/script.py --train

Testing process

Download pretrained model and put it into ./checkpoints/enlightening

Create directories ../test_dataset/testA and ../test_dataset/testB. Put your test images on ../test_dataset/testA (And you should keep whatever one image in ../test_dataset/testB to make sure program can start.)

Run

python scripts/script.py --predict

Dataset preparing

Training data [Google Drive] (unpaired images collected from multiple datasets)

Testing data [Google Drive] (including LIME, MEF, NPE, VV, DICP)

And [BaiduYun] is available now thanks to @YHLelaine!
