Paper Abstract

A new region growing based algorithm for extracting roads in spaceborne synthetic aperture radar (SAR) images is presented in this paper. The basic idea is that an initial seed point moves in a determined direction with a certain step length. The algorithm is composed of five sequential steps: the first is to search initial seed point and the second is to choose a circular window size similar to the width of the first road. In the third step, the criteria for region growing are chosen, and the fourth is to determine the key elements of new roads growing. At last, stopping rules are specified. The experimental results show that the proposed method can better extracted roads in SAR images.
