<p align="center"> <img src="figures/advantage.png"> </p><b>Left</b>: Compared with previous state-of-the-art methods, NeurOp achieves superior performance with only 28k parameters (~75% of CSRNet). <b>Right</b>: Strength Controllability Results. Our method can directly change the retouching output with intuitive control (i.e. directly modify the scalar strengths) <p align="center"> <img src="figures/result.png"> </p>

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)

Get Started

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
