It turns out that, at the bottom right of the project page<\/strong><\/a> I pointed to in my previous post<\/a>, there’s a link to a Windows implementation of their system. I hadn’t noticed that; thanks to James Hung-Kuo Chu, first author of the work, for the tip-off. He has a nice example of a colored QR code on his web page<\/a>.<\/p>\n\n\n\n

The Windows program works! Set a URL or text to search, upload a picture, ask for a QR code.

Here’s an example. Blur your eyes to help you figure out what well-known computer graphics image it represents. I find you’ll want to have the QR code be not very large in your camera’s view for it to be detected as one.<\/p>\n\n\n\n

A smaller one, of me. Again, blur eyes. When changing the size it’s likely best (?) to “pixel resize” (sample and hold, etc.), not resampling.<\/p>\n\n\n\n

Addendum: James Hung-Kuo Chu, the first author on the paper, noted that using the “Apply contrast enhancement” can give a better result. Here’s one with that:<\/p>\n\n\n\n

Addendum 5\/28\/2023: I just noticed this article<\/a>, pointing to another QR image generator<\/a>. The color one’s more fun, IMO, but I wanted to scribble down where this other tool is.
And addendum 6\/7\/2023: this cool QR maker<\/a> guided by Stable Diffusion (thanks to Andrew Glassner for pointing it out)<\/em>. Actual creator tool here<\/a>.
Also, 12\/14\/2023: a research topic<\/a> is to make a 2D barcode that tries to be more aesthetically pleasing than a QR code. Me, I think that ship has sailed – adopting a new barcode format seems unlikely – but, interesting topic and a view of “what might have been.”<\/p>\n","protected":false},"excerpt":{"rendered":"
