Abstract :
This work is concerned with extracting straight lines in SAR image areas for application of urban analysis. The methodology combines the Hough transform and line detector algorithms proposed by Tupin et al. (1998) to extract the main axes in road networks. A real SAR image is used to test the proposed algorithm.
