| Research Abstract |
We propose a novel example based marker free motion capture method. First, volume data of actor's body and its skeleton are obtained from multiple camera views at each frame through visual hull based method and thinning process. Then, examining the structure of the skeleton, we can acquire an attributed graph. By using a two-step graph matching algorithm with many example topological graphs, correspondences between body parts and skeleton parts are obtained. Finally, we estimate the position of the joints examining the curvature of the skeleton. The experiment result shows the validity our approach.
