3D Shape Matching Using Skeleton Graphs

We describe a method to match 3D polygonal geometry models using their internal skeleton graphs. These graphs carry information about the overall shape of the model. In order to make assumptions about the similarity of the 3D models, we search for the biggest common subgraph. As internal skeleton graphs normally do not consist of many edges, the problem of exponential time complexity due to NP ...

Skeleton Path Based Approach for Nonrigid 3D Shape Analysis and Retrieval

In this paper, we propose a skeleton path based approach to analyze and retrieve nonrigid 3D shapes. The main idea is to match skeleton graphs by comparing the geodesic paths between skeleton endpoints. Our approach is motivated by the fact that the path feature is stable in the presence of articulation of components. The experimental results demonstrate the performance of our proposed method i...

Skeleton-Based Shape Deformation Using Simplex Transformations

This paper presents a novel skeleton-based method for deforming meshes, based on an approximate skeleton. The major difference from previous skeleton-based methods is that they used the skeleton to control movement of vertices, whereas we use it to control the simplices defining the model. This allows errors, that occur near joints in other methods, to be spread over the whole mesh, giving smoo...

Skeleton-Based Shape Classification Using Path Similarity

Most of the traditional methods for shape classification are based on contour. They often encounter difficulties when dealing with classes that have large nonlinear variability, especially when the variability is structural or due to articulation. It is well-known that shape representation based on skeletons is superior to contour based representation in such situations. However, approaches to ...
