GFPGAN (CVPR 2021)

Colab Demo for GFPGAN ; (Another Colab Demo for the original paper model)
Online demo: Huggingface (return only the cropped face)
Online demo: Replicate.ai (may need to sign in, return the whole image)
We provide a clean version of GFPGAN, which can run without CUDA extensions. So that it can run in Windows or on CPU mode.

🚀 Thanks for your interest in our work. You may also want to check our new updates on the tiny models for anime images and videos in Real-ESRGAN 😊

GFPGAN aims at developing a 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.

🚩 Updates

✅ Integrated to Huggingface Spaces with Gradio. See Gradio Web Demo.
✅ Support enhancing non-face regions (background) with Real-ESRGAN.
✅ We provide a clean version of GFPGAN, which does not require CUDA extensions.
✅ We provide an updated model without colorizing faces.

PyTorch >= 1.7
Option: NVIDIA GPU + CUDA
Option: Linux

Installation

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

Clone repo

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

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

# If you want to enhance the background (non-face) regions with Real-ESRGAN,
# you also need to install the realesrgan package
pip install realesrgan

🏰 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.

You can find more models (such as the discriminators) here: [Google Drive], OR [Tencent Cloud 腾讯微云]

💻 Training

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

Tips

More high quality faces can improve the restoration quality.
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.)

Dataset preparation: FFHQ
Download pre-trained models and other data. Put them in the experiments/pretrained_models folder.
1. Pre-trained 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
Modify the configuration file options/train_gfpgan_v1.yml accordingly.
Training

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