Took tons of tweaking to get it to be readable, but the combination of using the original QR code in both the img2img and ControlNet inputs you can produce a working result with a little work.
I had to darken the midtones in Kirta afterward to get it to scan better, also works best if you put your phone further back.
The QR code was generated here with 30% error correction:
I was looking at this project last night. Definitely some cool images being used as QR's... IF they work, lol.
I'm surprised to not find more such QR-codes.
?w=768&ssl=1
is pretty slick, scans perfectly here and only gives away that it is indeed a QR-code via the calibration squares. Yours still looks blockier but smoother than theirs is definitely possible, too.
I specifically made mine around tiny stone blocks in the prompt to try to start from something that scans well and then work backward. Just trying out different weights and ranges with ControlNet and different models.
