Abstract: In this paper, we present a new method for extracting the 3D graph structure of gallery regions (worm-eaten areas) from x-ray CT images of wooden statues of Buddha. The extraction and analysis of these gallery regions by image processing is indispensable in the restoration of these historic and precious statues. Our new method consists of two parts: extraction of the initial 3D graph structure and its correction. Because the local shape of the statues and of the gallery regions can be similar, extraction of the gallery regions can create errors in the initial 3D graph structures. The second part of our method satisfactorily corrects both extraction errors and unsuitable extractions based on their local and global features. Our method can extract the 3D graph structures of gallery regions with high accuracy and can also be used to visualize these regions using extracted graph data.
