GFPGAN aims at developing Practical Algorithms for Real-world Face Restoration

GFPGAN (CVPR 2021)

1. Colab Demo for GFPGAN ; (Another Colab Demo for the original paper model)
2. We provide a clean version of GFPGAN, which can run without CUDA extensions. So that it can run in Windows or on CPU mode.

GFPGAN aims at developing Practical Algorithm for Real-world Face Restoration.
It leverages rich and diverse priors encapsulated in a pretrained face GAN (e.g., StyleGAN2) for blind face restoration.

:triangular_flag_on_post: Updates

• :white_check_mark: We provide a clean version of GFPGAN, which does not require CUDA extensions.
• :white_check_mark: We provide an updated model without colorizing faces.

:wrench: Dependencies and Installation

• Python >= 3.7 (Recommend to use Anaconda or Miniconda)
• PyTorch >= 1.7
• Option: NVIDIA GPU + CUDA
• Option: Linux (We have not tested on Windows)

Installation

We now provide a clean version of GFPGAN, which does not require customized CUDA extensions.
If you want want to use the original model in our paper, please see PaperModel.md for installation.

1. Clone repo

   git clone https://github.com/TencentARC/GFPGAN.git
   cd GFPGAN
   

2. Install dependent packages

   # Install basicsr - https://github.com/xinntao/BasicSR
   # We use BasicSR for both training and inference
   pip install basicsr
   
   # Install facexlib - https://github.com/xinntao/facexlib
   # We use face detection and face restoration helper in the facexlib package
   pip install facexlib
   
   pip install -r requirements.txt
   python setup.py develop
   

:zap: Quick Inference

Download pre-trained models: GFPGANCleanv1-NoCE-C2.pth

wget https://github.com/TencentARC/GFPGAN/releases/download/v0.2.0/GFPGANCleanv1-NoCE-C2.pth -P experiments/pretrained_models

Inference!

python inference_gfpgan.py --upscale_factor 2 --test_path inputs/whole_imgs --save_root results

:european_castle: Model Zoo

• GFPGANCleanv1-NoCE-C2.pth: No colorization; no CUDA extensions are required. It is still in training. Trained with more data with pre-processing.
• GFPGANv1.pth: The paper model, with colorization.

:computer: Training

We provide the training codes for GFPGAN (used in our paper).
You could improve it according to your own needs.

Tips

1. More high quality faces can improve the restoration quality.
2. You may need to perform some pre-processing, such as beauty makeup.

Procedures

(You can try a simple version ( options/train_gfpgan_v1_simple.yml) that does not require face component landmarks.)

1. Dataset preparation: FFHQ

2. Download pre-trained models and other data. Put them in the experiments/pretrained_models folder.

   1. Pretrained StyleGAN2 model: StyleGAN2_512_Cmul1_FFHQ_B12G4_scratch_800k.pth
   2. Component locations of FFHQ: FFHQ_eye_mouth_landmarks_512.pth
   3. A simple ArcFace model: arcface_resnet18.pth

3. Modify the configuration file options/train_gfpgan_v1.yml accordingly.

4. Training

python -m torch.distributed.launch --nproc_per_node=4 --master_port=22021 gfpgan/train.py -opt options/train_gfpgan_v1.yml --launcher pytorch
