A while ago I found a generator that took an image and a text and tried to use a genetic algorithm to evolve a QR code that looked like (a 2-bit dither of) the image. Unfortunately I’ve since lost the link, but I was quite impressed that it managed to generate a QR code for my then-employer’s URL that looked like their logo. Impressive what’s possible with a lot of error correction.
- magnat 8y agoHere is a paper and demo describing creation of such codes: http://vecg.cs.ucl.ac.uk/Projects/SmartGeometry/halftone_QR/halftoneQR_sigga13.html http://vecg.cs.ucl.ac.uk/Projects/SmartGeometry/halftone_QR/... Sadly, original online demo doesn't work anymore, but by looking for "halftone qr code" you'll find plenty of alternative implementations like this: http://jsfiddle.net/lachlan/r8qWV/ http://jsfiddle.net/lachlan/r8qWV/
