Extraction of building polygons from SAR images: Grouping and decision-level in the GESTALT System

The GESTALT-system is a stratified architecture for challenging computervision tasks. This contribution focuses on the 3rd and 4th layerof it - the grouping and decision layers. As example applicationbuilding recognition from high resolution SAR-data is presented.The 3rd layer contains an assessment driven perceptual grouping processwith any-time capability and flexible control. Important groupingprinciples such as good continuation and symmetry are utilized. Adynamic programming optimization is used in the final decision andpost-processing layer to find closed polygons that describe the outlinesof buildings. Further post processing includes polygon editing andconsistency enforcement.     «
