In view of the fact that roads in high resolution SAR image are hard to effectively extract, this paper proposes a new algorithm for road extraction in high resolution SAR image, which combines parametric kernel gragh cuts and mathematical morphology. First of all, the roads in the SAR image are initially segmented using parametric kernel gragh cuts, and void spots are filled and road edge is smoothed by mathematical morphology; secondly, road extraction is obtained by the degree of matrix, the improved len...
