Neural Color Operators for Sequential Image Retouching (ECCV2022)

[Pytorch Implementation]

[Jittor Implementation]

Left: Compared with previous state-of-the-art methods, NeurOp achieves superior performance with only 28k parameters (~75% of CSRNet). Right: Strength Controllability Results. Our method can directly change the retouching output with intuitive control (i.e. directly modify the scalar strengths)

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
│   ├── EX
│   └── VB
├── dataset-lite
│   ├── testA
│   ├── testB
│   ├── trainA
│   └── trainB
└── dataset-ppr
    ├── ppr-a
    ├── ppr-b
    ├── 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
