Abstract :
The extraction of road networks from synthetic aperture radar imagery is of fundamental importance for geospatial applications. The methods basically go through the steps such as road sharpening, road finding, road tracking and road linking. In this paper, a new global approach to road detection that is motivated by Kohonen neural network is proposed. It makes the joint of the roads more fluent and reduces detection errors. The computer simulation results show the highest extraction quality from the real SAR images.
