QR should look MORE like QR, and always include an URL next to it. If you display a QR Code with some url, and fail to show a shortened url next to it for people to type instead of scanning, you either fail basic common sense tests, or are intentionally being an asshat.

... or the QR code isn't meant exclusively for direct human consumption? A QR code is quite information-dense. With even the highest error-correction rates, a 53x53 QR code will store 100 bytes of information ( https://www.qrcode.com/en/about/version.html ). That's more than you can replicate in a URL intended for typing. For the case of the 'Show HN' here, think of semi-automatic uses of the QR code that still use t…

I've long wondered whether you can make a photo that gets recognized as a QR code by computers. This is very cool! Is there any way you can smooth out the calibration squares?

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

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.

That might be true. What would you suggest as a better description.

"Picture to QR code converter"?

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!

It’s my opinion that underutilization is because of application rather than any more ephemeral thing like appearance. QR codes haven’t had a killer app yet, and they tend to be used for marketing rather than any critical tasks that rely on the qualities that make it a useful technology. My guess is this will change as it’s become more or less a requirement to have a cell phone to function in western society.

That's really clever. Using the 4 example images at the top, the first (color) and last (B&W) work flawlessly on my iPhone. But the two animated ones in the middle will work for a second, and then the phone loses it. Animated seems like "too much" for a phone to lock on to -- perhaps just stick to static? That's cool enough.

With my Pixel 2, only the B&W worked with Google Lens.

I couldn't get any of them to work with my Pixel 3, using Google Lens.

Really sorry to hear that. I do not have such a device and without. If I knew which engine was being used I might have a starting point to figure out what might be happening.

edit: I noticed that the QR needs to contain a message or it will not scan.

I think that time has already arrived... I remember seeing reports that a cellphone was generally the most-valued item amongst the homeless in the US.

(Not quite a quantitative study, but here's an article on the importance of cellphones for homeless people, and challenges they face: https://www.calhealthreport.org/2019/01/11/expired-lost-stol... )

As an European I’d say over half of my mobile payments are already via a QR code (it triggers a direct debit from my bank app). It’s infinitely faster than going through online checkout forms.

Slightly OT, but when migrating data between iPhones, the old iPhone displays an animated point cloud that appears to function like a QR code. You scan it with the new phone, and your data starts to migrate locally through Bluetooth. Other than aesthetics, what are the advantages of the point cloud? Higher bandwidth? Also, if you were to transfer 100s of megabytes of data from device A to B, using A's display and B's…

Here is a good demo of a streaming qr solution. Not ours but a good demo of the concept. https://youtu.be/_0djJ1aVEXs We use a similar method for offline wallet transfers of private crypto keys. I’ll note a couple things. Keep the frame simple and not too dense. Be careful on ecc settings. Higher res camera androids to be slower in our testing. Be ready to loop the series to catch missed frames. Gives your frames and…
