UCSD DARPA Shredder Challenge Team

DARPA's Shredder Challenge aims to solve the most challenging jigsaw puzzles ever posed: the reconstruction of destroyed documents confiscated in war zones. The reward for piecing together the shredded documents is $50,000. Our team at the University of California - San Diego (UCSD) is combining advanced computer vision methods with shared tasking and referral-based crowdsourcing. If UCSD team wins, the money will be split among the participants who helped reconstruct the shredded documents and the participants who recruited them!
