If you want to use the paper model, please go to this Colab Demo for MM-RealSR .

• Python >= 3.7 (Recommend to use Anaconda or Miniconda)
• PyTorch >= 1.7

1. Clone repo

   git clone https://github.com/TencentARC/MM-RealSR.git
   cd MM-RealSR

2. Install dependent packages

   # Install basicsr - https://github.com/xinntao/BasicSR
   # We use BasicSR for both training and inference
   pip install basicsr
   # facexlib and gfpgan are for face enhancement
   pip install facexlib
   pip install gfpgan
   pip install -r requirements.txt
   python setup.py develop

python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 mmrealsr/train.py -opt options/MMRealSRNet_x4.yml --launcher pytorch --auto_resume
python -m torch.distributed.launch --nproc_per_node=4 --master_port=4321 mmrealsr/train.py -opt options/MMRealSRGAN_x4.yml --launcher pytorch --auto_resume

Please download checkpoints from Google Drive or Github Release.

python inference_mmrealsr.py -opt (path to .yml file) --im_path (path to LR images) --model_path (path to checkpoint) --res_path (path to save SR images)
python Metric/LPIPS.py --folder_gt (path to HR images) --folder_restored (path to SR images)
python Metric/NIQE.py --folder_restored (path to SR images)
python Metric/DISTS.py --folder_gt (path to HR images) --folder_restored (path to SR images)

Results are in the results folder

Quick start can be found in Colab Demo for MM-RealSR .
