; (Another [Colab Demo](https://colab.research.google.com/drive/1Oa1WwKB4M4l1GmR7CtswDVgOCOeSLChA?usp=sharing) for the original paper model) > :rocket: **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](https://github.com/xinntao/Real-ESRGAN/blob/master/docs/anime_video_model.md)** :blush: 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. :question: Frequently Asked Questions can be found in [FAQ.md](FAQ.md). :triangular_flag_on_post: **Updates** - :white_check_mark: Add [RestoreFormer](https://github.com/wzhouxiff/RestoreFormer) inference codes. - :white_check_mark: Add [V1.4 model](https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.4.pth), which produces slightly more details and better identity than V1.3. - :white_check_mark: Add **[V1.3 model](https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.3.pth)**, which produces **more natural** restoration results, and better results on *very low-quality* / *high-quality* inputs. See more in [Model zoo](#european_castle-model-zoo), [Comparisons.md](Comparisons.md) - :white_check_mark: Integrated to [Huggingface Spaces](https://huggingface.co/spaces) with [Gradio](https://github.com/gradio-app/gradio). See [Gradio Web Demo](https://huggingface.co/spaces/akhaliq/GFPGAN). - :white_check_mark: Support enhancing non-face regions (background) with [Real-ESRGAN](https://github.com/xinntao/Real-ESRGAN). - :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. --- If GFPGAN is helpful in your photos/projects, please help to :star: this repo or recommend it to your friends.

--- ## :wrench: Dependencies and Installation - Python >= 3.7 (Recommend to use [Anaconda](https://www.anaconda.com/download/#linux) or [Miniconda](https://docs.conda.io/en/latest/miniconda.html)) - [PyTorch >= 1.7](https://pytorch.org/) - Option: NVIDIA GPU + [CUDA](https://developer.nvidia.com/cuda-downloads) - 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](PaperModel.md) for installation. 1. Clone repo ```bash git clone https://github.com/TencentARC/GFPGAN.git cd GFPGAN ``` 1. Install dependent packages ```bash # 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 ``` ## :zap: Quick Inference We take the v1.3 version for an example. More models can be found [here](#european_castle-model-zoo). Download pre-trained models: [GFPGANv1.3.pth](https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.3.pth) ```bash wget https://github.com/TencentARC/GFPGAN/releases/download/v1.3.0/GFPGANv1.3.pth -P experiments/pretrained_models ``` **Inference!** ```bash python inference_gfpgan.py -i inputs/whole_imgs -o results -v 1.3 -s 2 ``` ```console Usage: python inference_gfpgan.py -i inputs/whole_imgs -o results -v 1.3 -s 2 [options]... -h show this help -i input Input image or folder.

✓better results on very low-quality inputs
✓ work on relatively high-quality inputs
✓ can have repeated (twice) restorations | ✗ not very sharp
✗ have a slight change on identity | |V1.2 | ✓ sharper output
✓ with beauty makeup | ✗ some outputs are unnatural | You can find **more models (such as the discriminators)** here: [[Google Drive](https://drive.google.com/drive/folders/17rLiFzcUMoQuhLnptDsKolegHWwJOnHu?usp=sharing)], OR [[Tencent Cloud 腾讯微云](https://share.weiyun.com/ShYoCCoc)] ## :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](https://github.com/NVlabs/ffhq-dataset) 1. Download pre-trained models and other data. Put them in the `experiments/pretrained_models` folder. 1.
