Abstract

3D object classification often requires extraction of a global shape descriptor in order to predict the object class. In this work, we propose an alternative part-based approach. This involves automatically decomposing objects into semantic parts, creating part graphs and employing graph kernels on these graphs to classify objects based on the similarity of the part graphs. By employing this bottom-up approach, common substructures across objects from training and testing sets should be easily identifiable and may be used to compute similarities between objects. We compare our approach to state-of-the art methods relying on global shape description and obtain superior performance through the use of part graphs.
