Chu Bing-zhi · Computer Engineering and Applications Journal · 2011
Based on Multi-resolution Reeb Graph(MRG) theory,it adopts the geodesic function to segment the 3D models,and then the skeleton of Reeb graph which indicates the topological structure of 3D model is generated.This method transforms Reeb graph to a tree structure,and then acquire the geometrical features by computing the discrete curvatures of corresponding segments for each critical point in skeleton.Combining the topology structure and geometric details an optimized similarity and difference functions is proposed.The experimental results show the robustness and efficiency of the method in 3D models similarity matching.
