An anonymous reader writes: A crease can ruin an often-irreplaceable printed photograph. But new research from HP Labs points towards a future where this is much less of a problem. Scientists at HP 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.
