Introduction

Single Image Super-Resolution (SISR) usually only does well in either objective quality or perceptual quality, due to the perception-distortion trade-off. In this paper, we proposed a two-stage model trained with low-frequency constraint and designed ADMM algorithm. Experimentally. our method achieve high perfromance in both PSNR/SSIM (objective quality) and NRQM/LPIPS (perceptual quality). Check followings for details.

pip install -r requirements.txt

Data Preparation

• Download testing data from Google Drive
• Put data under folder or change the dir value in
  (Temporally does not support to test self-collected data)

Testing

• Download trained model and put it under the folder models.
• Run following command

python test.py --scale 4 --save test_results --templateD HAN --templateP Clique \
--dir_data [root of testing sets] --data_test Set5+Set14+B100+Urban100 \
--pre_train ../models/model_trained.pt --save_results

We also provide the testing results in our paper.
