Approximation of Ridges and Umbilics on Triangulated Surface Meshes Reference

RidgesMechPartDetail.png
Marc Pouget and Frédéric Cazals
Global features related to curvature extrema encode important informations used in segmentation, registration, matching and surface analysis. Given pointwise estimations of local differential quantities, this package allows the approximation of differential features on a triangulated surface mesh. Such curvature related features are curves: ridges or crests, and points: umbilics.
