Datasets

Pretrain data to initialize our neurOps is hosted on 百度网盘 (code:pld9).

MIT-Adobe FiveK & PPR10K

We host all these data in 百度网盘 (code:jvvq)

• There are two preprocessed versions of MIT-Adobe FiveK, in our paper, we refer them as MIT-Adobe FiveK-Dark (originally provided by CSRNet) and MIT-Adobe FiveK-Lite (originally provided by Distort-and-Recover).

• The official PPR10K dataset link is here.

Get Started

• Clone this repo

  git clone https://github.com/amberwangyili/neurop
  

• Download the Dataset from 百度网盘 (code:jvvq) and unzip in project folder

  tree -L 2 neurop/datasets
  # the output should be like the following:
  datasets/
  ├── dataset-dark
  │   ├── testA
  │   ├── testB
  │   ├── trainA
  │   └── trainB
  ├── dataset-init
  │   ├── BC

      ├── ppr-c
      ├── testA
      ├── testM
      ├── trainA
      └── trainM
  

• Install Dependencies

  cd neurop
  pip install -r requirements.txt 
  

Test

1. We provide pretrained model weights for MIT-Adobe FiveK and PPR10K in pretrain_models

2. Run command:

   python test.py -config ./configs/test/<configuaration-name>.yaml 
   

3. The evaluation results will be in the neurop/results folder

Train

1. Initialization individual neural color operators:

   python train.py -config ./configs/init_neurop.yaml 
   

2. Finetune with strength predictors:

   python train.py -config ./configs/train/<configuration-name>.yaml
