HPL-2009-37 Photo Repair and 3D Structure from Flatbed Scanners - Pintus, Ruggero; Malzbender, Thomas; Wang, Oliver; Bergman, Ruth; Nachlieli, Hila; Ruckenstein, Gitit
Keyword(s): Scanners, 3D reconstruction, photo repair, photometric stereo
Abstract: We introduce a technique that allows 3D information to be captured from a conventional flatbed scanner. The technique requires no hardware modification and allows untrained users to easily capture 3D datasets. Once captured, these datasets can be used for interactive relighting and enhancement of su ...
