Ask HN: Are photos unique enough to use as QR codes?

1 points by quantum2022 2 years ago | 3 comments

I had a dream where I was holding a photograph that when you looked at it moved like a video. That spurred this idea where you could print a photo off of a video at any time during the video and then if you scanned the photo with your phone it would take you to the video. Could that be possible in the future? I know you could have a QR code in the corner of the photo perhaps, I just wasn't sure if a photo would be unique enough to use as an identifier somehow. Thanks.

Using an image as a search key is possible now. Google has a reverse image search and photo sites like Getty regularly search for people plagiarizing thier ip.

It seems reasonable to st sometime it will be possible to find a video from a still in a similar way to finding an audio track from a small clip.

Thanks for the kind response. My thought was creating a QR code using shapes in the image. Say a QR code is made up of 1000 shapes. A common theme in art is to draw using shapes. Take the 1000 largest 'shapes' in an image and create the QR code out of that instead of the type of QR codes we have now. On the other end there could be a catalog of what shapes match the video and it narrows down until it matches perfectly. I suppose you could use the QR code not just to link to videos, but to places in space on a maps or other things using a photo instead of a QR code. Again, thanks for your response.
