Using software, of course. The context is shredded and torn East German Stasi documents, but the technology is more general of course:
The machine-shredded stuff is confetti, largely unrecoverable. But in May 2007, a team of German computer scientists in Berlin announced that after four years of work, they had completed a system to digitally tape together the torn fragments. Engineers hope their software and scanners can do the job in less than five years even taking into account the varying textures and durability of paper, the different sizes and shapes of the fragments, the assortment of printing (from handwriting to dot matrix) and the range of edges (from razor sharp to ragged and handmade.) "The numbers are tremendous. If you imagine putting together a jigsaw puzzle at home, you have maybe 1,000 pieces and a picture of what it should look like at the end," project manager Jan Schneider says. "We have many millions of pieces and no idea what they should look like when we're done."
