摘要: This paper presents a new method for extracting topographic features from images approximated by triangular meshes. Peaks, pits, passes, ridges, valleys, and flat regions are defined considering the topological geometric relationship between elements. The approach is suitable several computer-based recognition tasks, such as geographic information systems, rapid prototyping, computer graphics, reverse engineering. has been applied to wide range of images, producing good compromise accuracy time requirements.
