Update

  • 2022.10.10 Release reproduce training log for SR stage in wandb. Reach similar performance as the paper, LPIPS: 0.329 @415k for div2k (x4).
  • 2022.09.26 Add example training log with 70k iterations wandb
  • 2022.09.23 Add colab demo google colab logo
  • 2022.07.02
    - Update codes of the new version FeMaSR
    - Please find the old QuanTexSR in the quantexsr branch

Here are some example results on test images from BSRGAN and RealESRGAN.


Left: real images | Right: super-resolved images with scale factor 4

Dependencies and Installation

  • Ubuntu >= 18.04
  • CUDA >= 11.0
  • Other required packages in requirements.txt
# git clone this repository
git clone https://github.com/chaofengc/FeMaSR.git

# install python dependencies
pip3 install -r requirements.txt
python setup.py develop

Quick Inference

python inference_femasr.py -s 4 -i ./testset -o results_x4/
python inference_femasr.py -s 2 -i ./testset -o results_x2/

Train the model

Preparation

Dataset

Please prepare the training and testing data follow descriptions in the main paper and supplementary material. In brief, you need to crop 512 x 512 high resolution patches, and generate the low resolution patches with degradation_bsrgan function provided by BSRGAN. While the synthetic testing LR images are generated by the degradation_bsrgan_plus function for fair comparison.

Model preparation

Before training, you need to

  • Download the pretrained HRP model: generator, discriminator
  • Put the pretrained models in experiments/pretrained_models
  • Specify their path in the corresponding option file.

Train SR model

python basicsr/train.py -opt options/train_FeMaSR_LQ_stage.yml

Model pretrain

In case you want to pretrain your own HRP model, we also provide the training option file:

python basicsr/train.py -opt options/train_FeMaSR_HQ_pretrain_stage.yml
