FreeU for Fooocus

[kubilaykilinc]

Would it be possible to include FreeU in Fooocus? or can be added as an option.

code : https://github.com/ChenyangSi/FreeU

This is something new though. I don't think it's fully seated yet. It has a positive contribution for SD 1.5 and 2.1. but I don't know for SDXL 1.0. I'll test it a bit on comfyUI. Still, I wanted to write this idea here.

Sounds great.

That indeed sounds most excellent! Does anyone know how to use it with Fooocus in the meantime?

MEMO to keep back things
i add back here the references found on their github (Chnyangsi):
FreeU connected between Checkpoint and Ksampler with 4 parameters as B1, b2 and s1, s2

• @murphylanga147
• the B values (around 1) control the style and image quality as the S control the quality/number (e.g. number of legs of an animal) of the objects on the image
• best results with values around and higher for S1 and with low values between 0-0.3 for S2.
• When the distance between S1 and S2 becomes smaller, more and more objects are generated.
• ... tiny details and textures are the S, and the larger blobs are B

  If you tried FreeU and want to share your results, let me know and we can put up the link here.

SDXL from Nasir Khalid:
b1 = 1.1 - b2 = 1.2 - s1 = 0.6 - s2 = 0.4

How exactly should this be used?
Do I turn select NONE for Refiner if I use FreeU?

You can find some examples illustrating how you can use FreeU in MRE wiki. Results in original Fooocus for the same values might be a bit different, because I've updated FreeU node to v2 in Fooocus v2.1.701 (#727).
