Coherent skeleton extraction for time varying surfaces
Pang Zhiqian · Journal of Computer Applications · 2014
Concerning the low efficiency and non-coherency in extracting skeletons of time varying surfaces, a new method through applying a registration based propagation strategy to repair the incomplete initial skeletons was proposed in this paper. Firstly, complete skeletons for the key frames of the time varying surfaces were extracted, the initial skeleton series for the surfaces between the key frames were directly extracted. Then a global skeleton alignment method was designed and used to warp key skeleton to its neighboring skeletons. Finally, the information of the warped key skeleton was transferred to its neighboring skeletons, and a complete skeleton was produced. The entire skeleton series were processed by this process to produce complete skeletons. The experimental results show that this system is efficient and accurate. This system can be applied to the raw scanned dynamic geometry data with significant noise, outliers, and large areas of missing data, but still can receive time coherent skeleton series.
