Model overview

gfpgan is a practical face restoration algorithm developed by the Tencent ARC team. It leverages the rich and diverse priors encapsulated in a pre-trained face GAN (such as StyleGAN2) to perform blind face restoration on old photos or AI-generated faces. This approach contrasts with similar models like Real-ESRGAN, which focuses on general image restoration, or PyTorch-AnimeGAN, which specializes in anime-style photo animation.

Model inputs and outputs

gfpgan takes an input image and rescales it by a specified factor, typically 2x. The model can handle a variety of face images, from low-quality old photos to high-quality AI-generated faces.

Inputs

  • Img: The input image to be restored
  • Scale: The factor by which to rescale the output image (default is 2)
  • Version: The gfpgan model version to use (v1.3 for better quality, v1.4 for more details and better identity)

Outputs

  • Output: The restored face image

Capabilities

gfpgan can effectively restore a wide range of face images, from old, low-quality photos to high-quality AI-generated faces. It is able to recover fine details, fix blemishes, and enhance the overall appearance of the face while preserving the original identity.

What can I use it for?

You can use gfpgan to restore old family photos, enhance AI-generated portraits, or breathe new life into low-quality images of faces. The model's capabilities make it a valuable tool for photographers, digital artists, and anyone looking to improve the quality of their facial images. Additionally, the maintainer tencentarc offers an online demo on Replicate, allowing you to try the model without setting up the local environment.

Things to try

Experiment with different input images, varying the scale and version parameters, to see how gfpgan can transform low-quality or damaged face images into high-quality, detailed portraits. You can also try combining gfpgan with other models like Real-ESRGAN to enhance the background and non-facial regions of the image.

realesrgan is a practical image restoration algorithm developed by the Tencent ARC Lab. It aims to develop effective algorithms for general image/video restoration, extending the powerful ESRGAN model to practical real-world applications. realesrgan is trained using only synthetic data, but can achieve impressive results on real-world low-resolution images, outperforming traditional super-resolution methods. realesrgan can be considered an improved version of the ESRGAN model, with enhancements for real-world applicability. It performs well on natural images as well as anime/cartoon-style images, thanks to its versatile training approach. Unlike the face-specific GFPGAN and Codeformer models, realesrgan can be applied to a broader range of image types. Model inputs and outputs Inputs img**: The input image, which can be a URI to an image file. tile**: The tile size to use for processing the image. Setting this to a non-zero value can help with GPU memory issues, but may introduce some artifacts. scale**: The desired upscaling factor, typically 2x or 4x. version**: The version of the realesrgan model to use, such as the general "General - v3" or the anime-optimized "RealESRGAN_x4plus_anime_6B". face_enhance**: A boolean flag to enable face enhancement using the GFPGAN model. This is not recommended for anime/cartoon-style images. Outputs The upscaled and restored output image, returned as a URI. Capabilities realesrgan can effectively restore and upscale a variety of image types, from natural scenes to anime/cartoon-style images. It can handle noise, blur, and other common degradations, producing high-quality results.
