> Next, they fed existing QR codes into the Stable Diffusion AI image generator and used ControlNet to maintain the QR code's data positioning despite synthesizing an image around it, likely using a written prompt.
A few months ago, after seeing that ChatGPT could produce reasonably accurate MD5 hashes, I tried generating QR codes with a Midjourney prompt. It failed in a really interesting way - it generated _symmetric_ QR codes, even though QR codes are explicitly designed to be asymmetric (think of the timing pattern, the three large blocks). So while I could claim ChatGPT "understood" MD5 hashes, I can't claim that Midjourney "understands" QR codes.
How long until generative models can produce working QR codes on their own?
- IceWreck 3y agoForget QR codes, until very recently Stable Diffusion and Co could not generate legible text in images.
- dustypotato 3y agoCan they now? I had the impression that stabled diffusion is not moving forward that fast because the original team that built it is not the ones that are in stability.ai
- IceWreck 3y agosome guy in /r/stablediffusion made a lora that can do that (or maybe a derivative model, dont remember which)
- fennecfoxy 3y agoIt's the human handwriting vs computer font problem. We can't expect a font out of ML, only handwriting.
