Motion segmentation of dynamic 3D mesh is presented.A dynamic 3D mesh is a sequence of 3D models made for a real-world dynamic object.Since 3D models are generated independently regardless of their neighboring frames,motion tracking by taking correspondence of vertices between 3D models is very difficult.Therefore,a feature-vector-based motion degree analysis is used.For this purpose,a modified shape distribution algorithm has been developed.In the algorithm,representative points are generated by clustering vertices based on their spatial distribution instead of randomly sampling vertices as in the original shape distribution algorithm.Motion segmentation is conducted by searching local minima in the degree of motion calculated in the feature vector space.A simple verification process is also presented.Experiments using a dynamic 3D mesh of traditional dances demonstrated high accuracy of motion segmentation with precision and recall rates of 92% and 87%.
