From: Virtual cleaning and unwrapping of non-invasively digitized soiled bamboo scrolls
(a) Photograph of exemplary bamboo scrolls located at the Changsha Bamboo Slips Museum, Changsha, Hunan. (b) Used bamboo scroll covered and filled with potting soil and packed in a plastic bag for the experiments. The carvings were contaminated by pressing the soil onto the surface to create the worst case scenario. (c) The 3-D X-ray CT measurement setup: The X-ray source and the flat panel detector are fixed while the object rotates around the z-axis. The object is completely covered by the X-rays emitted to the detector such that it can be fully visualized in the reconstructed volume. The scroll is placed upright such that a constant ray length through the object is given aiming to reduce artifacts.
