An Approach for Road Extraction from High Resolution Imagery Based on Radon-Like Features and Mathematical Morphology

摘要

Road Extraction from high resolution imagery is of fundamental importance in the context of spatial data capturing and updating for GIS applications. In this paper we present a new approach for extracting roads from high resolution imagery using Radon-like features and mathematical morphology. In this approach first image is preprocessed using bilateral filter and then Radon-like features are used to enhance the road edges. Finally roads are extracted using morphological operations. The method is successfully implemented using high resolution satellite and areal imagery.
