QArt – Pictures in QR code with no inherent errors

• hdhzy 9y ago
  Excellent post! Months ago when I saw gopher QR code I was wondering how is it possible to encode picture like that but found nothing.

  the article points to google code, is there another source? (gitlab, github, bitbucket, etc)

    AFAIK, no.

    The code was exported to GitHub, to which I assume is the author's account (rsc): https://github.com/rsc/qr https://github.com/rsc/qr However, I'm not familiar with go and all I see there, is what looks like a plain QR encoding library. There is also code for the web server: https://github.com/rsc/swtch/blob/master/app/blog/qr.go https://github.com/rsc/swtch/blob/master/app/blog/qr.go Again, I don't know how to dig further to find the source of the qrweb module. Any ideas?

  Other interesting technique is using halftones/dithering to embed picture in readable QR code: PDF paper: http://vecg.cs.ucl.ac.uk/Projects/SmartGeometry/halftone_QR/paper_docs/halftoneQR_sigga13.pdf http://vecg.cs.ucl.ac.uk/Projects/SmartGeometry/halftone_QR/...

  It would be interesting to see traffic signs created this way. Readable both by humans and by machines from far away.
