The script creates a web UI for Stable Diffusion's txt2img and img2img scripts. Following are features added
that are not in original script.
### GFPGAN
### Extras tab
Additional neural network image improvement methods unrelated to stable diffusion.
#### GFPGAN
Lets you improve faces in pictures using the GFPGAN model. There is a checkbox in every tab to use GFPGAN at 100%, and
also a separate tab that just allows you to use GFPGAN on any picture, with a slider that controls how strongthe effect is.
![](images/GFPGAN.png)
#### Real-ESRGAN
Image upscaler. You can choose from multiple models by original author, and specify by how much the image should be upscaled.
Requires `realesrgan` librarty:
```commandline
pip install realesrgan
```
### Sampling method selection
Pick out of three sampling methods for txt2img: DDIM, PLMS, k-diffusion:
Pick out of multiple sampling methods for txt2img:
