StableDiffusionWebUI: Old Photo Restoration (GFPGAN)

Preface

One of the use cases for sdwebui is old photo restoration.

In fact, common old photo restoration tools existed before sdwebui:

GFPGAN: https://github.com/TencentARC/GFPGAN

CodeFormer: https://github.com/sczhou/CodeFormer

However, combining them with Hires.fix in sdwebui yields even better results.

Extras

sdwebui conveniently places some common features in the Extras tab.

This section focuses on GFPGAN and CodeFormer.

Upload Old Photo

Under the Extras tab, in the first area you can click or drag and drop an old photo.

Image Upscaling

In the second area, select the image upscaling algorithm and other parameters.

Here we choose ESRGAN-4x. For other algorithms, see: https://blog.vincentqiao.com/sd-hiresfix-m

Set the scale factor to 4x.

GFPGAN

Simply check the box, and sdwebui will automatically download the GFPGAN-related files.

The upscaling result is shown below. Personally, I think the result is quite good.

CodeFormer

Similarly, just check the box, and sdwebui will automatically download the CodeFormer-related files.

The upscaling result is shown below. It doesn’t seem as good as GFPGAN, mainly because the glasses area is slightly distorted.

Summary

For old photo upscaling tasks, the recommended configuration is:

Upscaling algorithm: ESRGAN-4x

Upscaling tool: GFPGAN
