We propose a new approach for automatic road extraction from aerial imagery with a model and a strategy mainly based on the multi-scale detection of roads in combination with geometry-constrained edge extraction using snakes. A main advantage of our approach is, that it allows for the rst time a bridging of shadows and partially occluded areas using the(More)
This paper proposes an approach for automatic road extraction in aerial imagery which exploits the scale-space behavior of roads in combination with geometric constrained snake-based edge extraction. The approach not only has few parameters to be adjusted, but for the first time allows for a bridging of shadows and partially occluded areas using the heavily(More)
An approach for real-time object recognition in digital images based on the principle of the generalized Hough transform is proposed. It combines robustness against occlusions, distortions, and noise with invariance under rigid motion and local illumination changes. The computational effort is reduced by employing a novel efficient limitation of the search(More)
In January 2004 the High Resolution Stereo Camera (HRSC) on board the ESA mission Mars Express started imaging the surface of planet Mars in colour and stereoscopically in high resolution. The Institute of Photo-grammetry and GeoInformation (IPI) of the University of Hannover and the Chair for Photogrammetry and Remote Sensing (LPF) of the Technische(More)
