The codes are generated on their backend in a C program, but I don't see any reason why it couldn't be done in WASM.

Ultimately it should be made possible to do it locally. Current setting is low-quality and takes about 1-2 seconds. Mid-setting about 20 seconds and high about 20 minutes.

I must be missing something... What does this have to do with photo realism?

It uses dithering by Spacial Colour Quantification to get the best photorealistic 93x93/186x186 colour image. The title plays on that the QR can be near photo and not some pixelated icon.

This is really cool! I do wonder what the practical use is, though, aside from just being pretty cool. In a real world situation I think the recognizability of a QR code as something you can scan with your phone is an important part of the value.

Hiding information in plain sight :) Animations. Real life Games. Information stickers (like my photo containing contact information).

Related idea: https://www.aestheticodes.com/ https://www.youtube.com/watch?v=kW39Mt5kscQ But this is probably better because it uses natively supported QR codes.

I have a pet project, "Oh By"[1] that is a replacement for QR codes that does not require an app to create, or consume, and you can just chalk them up anywhere.

The downside is that it is a centralized service. Further, you would need to trust that this centralized service would continue operating into the indeterminate future. Luckily I have a strong track record there.

A very simple example use-case is here:

I has nothing to do with it. Unfortunately, OP is engaging in a cheap form of terminology hijacking.

Either that or OP has no idea what the word 'photorealism' means.

Either way OP is doing himself a disservice. Great project. Siraj-Raval vibes.

It's a front/back-end system. I'm currently running the backend on a c5a.xlarge instance.

Ah, I thought it's done client side. Never mind then.

Somehow, I think these kinds of "clever" QR codes would be less used. Most people aren't going to even notice that they are legit QR codes. QR codes are already underutilized enough, at least in western countries. Cool idea, though!
