Automatic Road Extraction From Remote Sensing Images Based on a Normalized Second Derivative Map

In this letter, we propose a novel automatic algorithm for road extraction from remote sensing images. The algorithm includes low- and high-level processing. In the low-level processing, we determine a normalized second derivative map of road profiles of a generalized bar shape, which is width invar...
