| 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 |

| ▲ | otaviogood 2 days ago | parent [-] | | 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 | | |
| ▲ | dylan604 2 days ago | parent | next [-] | | 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 | | |
| ▲ | otaviogood 2 days ago | parent [-] | | You might be reading into it too much. I think the originals were just random pieces of different kinds of paper. Graph paper, yellow lined, paper, blank white paper... I don't remember exactly, but I think the copies could be special paper with a colored backside so they would know which way was up really easily for the scanning process. | | |
| ▲ | dylan604 2 days ago | parent [-] | | no it was a deliberate what if meant in jest that probably really could have been kept to myself |

| ▲ | anitil 2 days ago | parent | prev [-] | | Did they scan both sides of the shreds? |
