A novel approach to the construction of motion graphs based on a new similarity measurement method is proposed in this paper. The main contributions of this paper are: i) to improve the accuracy of motion similarity computing, a new similarity measurement method is presented which combines frame distance based on dynamic time warping (DTW) with uniform warping window and motion distance based on motion features; ii) to avoid illogical jump of standard motion graph, a new automatic construction strategy of motion graphs based on similarity of motion clips is proposed, transition points of which are matched based on the path with the minimum cost and motions are synthesized based on motion transition points. Experimental results based on the CMU MoCap human motion database show that the proposed method can confirm the logical correctness and naturalness in the junction of two human locomotion sequences and its efficiency is two or three times faster than the standard motion graph.
