HP Restores Creased Photos With Flatbed Scanners

An anonymous reader writes "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." They're using multiple light sources to do this, in a way that reminds me of last year's description of 3D image creation using an ordinary digital camera.

Won't this ruin my collection of photographs of creased paper?

Actually, no, it won't. Since the method uses different light sources to build a partial 3D model of the actual shape of the crease, your mere photographic creases won't be detected. You can breathe a sigh of relief.
