Automatic interpretation of laser scanner data for building detection and map updating was studied. Digital surface and terrain models (DSM and DTM) and an intensity image were created using a helicopter-borne TopEye system recording with 2–3 pulses per m. The DSM was segmented into homogeneous regions using a region-based segmentation method, and the segments were classified as `building ́, `tr...

Most change detection (CD) methods assume that prechange and postchange images are acquired by the same sensor. However, in many real-life scenarios, e.g., natural disasters, it is more practical to use latest available before after occurrence of incidence, which may be using different sensors. In particular, we interested combination optical synthetic aperture radar (SAR) SAR appear vastly fro...
