Toward the Recognition of Buildings and Roads on Aerial Photographs

Abstract

This paper describes steps toward the recognition of cultural features such as buildings and roads on aerial photographs. The approach involves several successive stages of grouping of edge segments. Straight line segments are fitted to sets of edge pixels; compatibilities between pairs of these segments, based on gray level and geometric information, are computed; and the segments are then grouped into building-like and road-like groupings based on these compatibilities. Examples of the results obtained using this approach are given, and some variations on the initial stages of the process are also investigated.
