Graph structure extraction of woormhole regions from CT images for the damage estimation of a wooden statue

Abstract

There are many cultural assets which are desired to being restored and preserved. One of the most damaged assets are wooden statues which have many fractures and wormholes caused by their material properties. Therefore, it is necessary to carry out the urgent restoration. In this paper we focus on the examination and estimation of wormholes We first present the three-dimensional graph representation of wormhole regions, and then extract the graph structures from the X-ray CT images.
