Abstract

In this work we evaluate purely structural graph measures for 3D object classification. We extract spectral features from different Reeb graph representations and successfully deal with a multi-class problem. We use an information-theoretic filter for feature selection. We show experimentally that a small change in the order of selection has a significant impact on the classification performance and we study the impact of the precision of the selection criterion. A detailed analysis of the feature participation during the selection process helps us to draw conclusions about which spectral features are most important for the classification problem.
