Accurate and Lightweight Image Super-Resolution with Model-Guided Deep Unfolding Network [IEEE] [homepage]

This repository is Pytorch code for our proposed MoG-DUN.

The code is built on RCAN and tested on Ubuntu 16.04 environment (Python 3.5/3.6/3.7, PyTorch 1.0.0/1.0.1, 9.0/10.0) with 2080Ti/1080Ti GPUs.

Requirements

• Python 3
• skimage
• imageio
• Pytorch (Pytorch version 1.0.1 is recommended)
• tqdm
• cv2 (pip install opencv-python)

Test

Quick start

Test on standard SR benchmark

1. If you have cloned this repository, the pre-trained models can be found in experiment fold and test dataset Set5 can be found in data fold.

2. Then, run command:

   cd code_AG
   sh test.sh
   

3. Finally, PSNR values are shown on your screen, you can find the reconstruction images in ../experiment/xx/results/
