Structural analysis of 3D digital shape using morphological skeleton

摘要

We propose a new feature extraction method called SIMS to analyze 3-D digital shapes. It is possible by using SIMS that the hierarchical analysis of 3-D digital shapes. It was difficult for performing recognition hierarchically by the conventional method using multi-resolution analysis. Because it has no robustness to phase change or a spatial change in low resolution. SIMS has robustness that needs to perform hierarchical recognition. SIMS is based on a Morphological skeleton. We verified the character of SIMS by quantitive experiment.
