Abstract

This paper presents an evaluation of the stability of the augmented multiresolution Reeb graph (aMRG) [2] for shape retrieval of 3D watertight models. The method is based on a Reeb graph construction which is a well-known topology based shape descriptor. Using multiresolution property and additive geometrical and topological informations, aMRG has shown its efficiency and robustness to retrieve high quality 3D models [3]. The SHREC — SHape REtrieval Contest 2008 Stability on Watertight Models Track data collection B is composed of 1500 models: 15 classes of 100 models. Each class contains original models and models with noise. We propose to evaluate the robustness of the aMRG with embedded topological features [4] with regards to the following perturbations: Gaussian noise, uneven re-sampling, small protrusions, and topological noise.
