Built-Up Area Feature Extraction: Second Year Technical Progress Report

Abstract

This report describes research on the analysis of aerial images. During this year we have built on previous research, in road network extraction and in the detection and delineation of buildings using monocular analysis. We have expanded our research in monocular analysis to include the detailed analysis of shadows. Our shadow analysis research has resulted in three techniques for the interpretation of monocular imagery: building prediction, grouping of related building hypotheses, and building hypothesis verification. In addition, we have implemented a technique to acquire estimates of building heights using the lengths of cast shadows. Keywords: Feature extraction; Scene interpretation; Monocular analysis; Built-up areas.
