Abstract

In this paper, we present an approach for extracting structured topological features from a triangular mesh manifold. These features include concentric rings of facets, which can be arranged in spiral-wise fashion. After describing the approach, the paper highlights the utility of such features in some applications related to 3D facial data processing. This include, assessing triangular mesh tessellations, detecting facial landmarks, computing geodesic features, and extracting shape descriptors. Experiments made with 3D facial data confirmed the great potential of this framework.
