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 by considering the topological and geometric relationship between the triangular elements. The approach is suitable for several computer-based recognition tasks, such as geographic information systems, rapid prototyping, computer graphics, and reverse engineering. The method has been applied to a wide range of images, producing a good compromise between accuracy and time requirements.
