Title:Extracting Second-Order Topographic Surface Features from Range Data
Date: 1990
Presented:Accepted for presentation at the 1990 British Machine Vision Conference, Oxford
Keywords:surface description
Abstract: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.
