Articulation constrained skeleton extraction of 3D models
关节特征约束的3维模型骨架提取算法

We propose an optimized articulation-constrained skeleton extraction approach based on multi-resolution Reeb graph(MRG)method.It overcomes the low efficiency of calculating the discrete contour constrictions of each vertex on a 3D model.Instead,it obtains the hyperbolic extreme points by analyzing the Gaussian curvature of each vertex and defines them as constrained points which imply the concave feature of the local surface,and the articulation feature areas are then extracted.Finally the Reeb graph is opt...
