Building reconstruction from a single DEM
We present a new approach for building reconstruction from a single Digital Elevation Model (DEM). It treats buildings as an assemblage of simple urban structures extracted from a...

SAR Image Registration and Segmentation Using an Estimated DEM
Abstract. Synthetic aperture radar SAR images are notoriously di cult to interpret. Segmentation is simpli ed if a digital map is available, to which the image can be registered....
