| Abstract: | Road extraction from remotely sensed images has always been a challenging problem. In this paper we present an approach for road extraction based on topological derivative and mathematical morphology. The road extraction scheme has three main steps: image segmentation using topological derivative, road cluster identification and road cluster filtering using mathematical morphology. |
