Over 10 years ago, in 2011, there was a DARPA shredder challenge: https://techcrunch.com/2011/12/02/all-your-shreds-are-belong...

I wonder how much the state of the art in reassembling shredded documents has advanced since then...

Exactly what I though of when I saw the title. I had totally forgotten about this! I was fresh out of school in 2011 working my first full time job and took a shot at this challenge on my own in my spare time with a very naive approach using Python and OpenCV; I was way out of my depth but managed to get my name on the (very bottom of the) leaderboard :-)

Nice

I was just thinking about this at lunch today! I have been working through the Advent of Code 2020 problems. Day 20 involves a very simple version of the reassembly problem, putting together square tiles with fixed size overlapping border patterns. I did the first phase of the challenge "by hand," but I was wondering how fast it would be with the recent advances in CNNs and Transformer models.
