HP Restores Creased Photos With Flatbed Scanners

I haven't seen this yet but it certainly sounds interesting: Scientists at Hewlett-Packard have developed a technique to detect creases in photographs using standard, unmodified flatbed scanners. Once correctly scanned into a computer, software can determine where the photograph's defect is, and artificially correct it to remove any trace of a crease or fold. The result is a spotless JPEG scan from a creased photo, with absolutely no modified hardware and no technical know-how required on the part of the user.
