Extracting second-order topograhic surface features from range data
Robert Bob Fisher · 1990
Second-order volumetric features (e.g. ridges, dents, bumps, etc) were previously defined to extend the SMS object modeling system. Here, we show that one can extract surface features from range data that can be described in this vocabulary of second-order features. The process is based on a classification of regions found by an approach based on local surface shape, and has a natural scale structure. Algorithms and results are given.
