Abstract :
This paper deals with the problem of road extraction in high resolution SAR data. The presented method is an improvement of previous works. The process is an almost automatic algorithm based on a Hough transform and a road tracking algorithm. The main limitations of the process are due to the road context. First investigations to exploit contextual information in the process are presented.
