Marked point process, Remote sensing, Building detection, Harris based active contour


In this paper we introduce a novel method for building localization and 2D outline extraction in remotely sensed images. A robust Marked Point Process (MPP) model attempts to detect and separate the individual building segments and gives a rough rectangular estimation about the geometry of each entity. The refinement of the detection is achieved by an active contour model, which is initialized by the convex hull of the Harris feature points extracted around the MPP step's output rectangles. The method is tested in real aerial images provided by the Hungarian Institute of Geodesy, Cartography and Remote Sensing.
