Me and my team used these yellow tracking dots to reconstruct shredded documents for a DARPA shredder challenge over a decade ago. You can see our program highlight the dots as we reconstruct the shredded docs. https://www.youtube.com/watch?v=uzZDhyrjdVo Thanks to that, we were able to win by a large margin. :)
Oh wow, I remember hearing about this challenge on Daily Planet when I was still in elementary school. It's super cool seeing a follow up, it brought back a hidden memory.
Super cool demo btw
and here I thought the library shredder/scanner in Vinge's Rainbows End was just sci-fi loosely based on gene sequencing...
(I mean it is, but seeing this almost real-world implementation is fun!)
what was the process of getting each of the shredded pieces scanned for your program to use. I'm guessing that process could have a write up on it just as much as the solver. there's definitely a personality type that can handle that type of mess
DARPA scanned the shreds. The funny thing is, they didn't want to shred the original paper, so first they photocopied the paper in a high quality color copier, shredded it, and scanned it. And that's where the little yellow dots came from. :D
interesting. now my brain is churning on why would they not want the originals shredded. what does that say about the value they placed on the originals? why would they open a contest up with documents of such perceived value as the content? being DARPA, i'm sure there's a reason though

Did they scan both sides of the shreds?
