Paper, Project Page & Dataset

Requirements

  1. Python
  2. Tensorflow >= 1.5.0
  3. numpy, PIL

Testing Usage

To quickly test your own images with our model, you can just run through

python main.py 
    --use_gpu=1 \                           # use gpu or not
    --gpu_idx=0 \
    --gpu_mem=0.5 \                         # gpu memory usage
    --phase=test \
    --test_dir=/path/to/your/test/dir/ \
    --save_dir=/path/to/save/results/ \
    --decom=0                               # save only enhanced results or together with decomposition results

Or you can just see some demo cases by

python main.py --phase=test

, the results will be saved under ./test_results/.

Training Usage

First, download training data set from our project page. Save training pairs of our LOL dataset under ./data/our485/, and synthetic pairs under ./data/syn/. Then, just run

python main.py
    --use_gpu=1 \                           # use gpu or not
    --gpu_idx=0 \
    --gpu_mem=0.5 \                         # gpu memory usage
    --phase=train \
    --epoch=100 \                           # number of training epoches
    --batch_size=16 \
    --patch_size=48 \                       # size of training patches
    --start_lr=0.001 \                      # initial learning rate for adm
    --eval_every_epoch=20 \                 # evaluate and save checkpoints for every # epoches
    --checkpoint_dir=./checkpoint           # if it is not existed, automatically make dirs
    --sample_dir=./sample                   # dir for saving evaluation results during training

Tips:

  1. The model is quite small, so it will take just minutes to finish the training procedure if you are using GPU. For people who are using CPU, it is also affordable.
  2. The enhancement performance is highly dependent on training parameters. So if you change the default parameters, you might get some weird results.
