摘要：In this part of literature we will present a new way of extracting a skeleton out of a point cloud. Our approach is based on looking at the attributes of data points in small parts of the space. The small space parts are derived by an octree subdivision. Out of these small parts we generate a graph which describes the structure. By treating this graph with replacement rules, we generate the skeleton out of it. During this procedure we generate the segmentation information too. At the end we will give a short overview of implementation issues and make a quick look into the future of this method
