An Approach to Building Extraction from Digital Surface Models
نویسنده
چکیده
Motivated by the test data sets of ISPRS WG III on image understanding we investigate the feasibility of building extraction using high resolutionDigital Surface Models DSM as input data which do not only contain information about the topographic surface like Digital Elevation Models DEM but also information about the buildings The steps of the proposed procedure increasingly use explicit domain knowledge speci cally geometric constraints in the form of parametric and prismatic building models The reconstruction of the prismatic models and the selection of the models are based on the principle of Minimum Description Length MDL In addition we also discuss the possible use of information from GIS or maps in our approach KURZFASSUNG Unsere Arbeiten bez uglich der Geb audeerfassung aus hochau osenden DigitalenOber achenmodellen die nicht nur Information uber die topographische Ober ache wie Digitale H ohenmodelle sondern auch uber Geb aude enthalten sind durch die von der ISPRS WG III herausgegebenen Testdatens atze angeregt worden Die Schritte des hier aufgezeigten Verfahrens nutzen Wissen uber Geb aude welches durch die verwendeten parametrischen und prismatischen Geb audemodelle repr asentiert wird Die Rekonstruktion der prismatischen Modelle und die Auswahl des f ur die Rekonstruktion anzuwendenden Modells basieren auf dem Prinzip der Minimalen Beschreibungl ange Desweiteren wird der Einsatz von GIS und Karten als zus atzliche Datenquelle im Zusammenhang mit der Geb audeerfassung aus Digitalen Ober achenmodellen diskutiert

There are several different methods to make an efficient strategy for steganalysis of digital images. A very powerful method in this area is rich model consisting of a large number of diverse sub-models in both spatial and transform domain that should be utilized. However, the extraction of a various types of features from an image is so time consuming in some steps, especially for training pha...
متن کاملExtracting Buildings from Digital Surface Models
This paper describes an approach for building extraction using Digital Surface Models (DSM) as input data. The first task is the detection of areas within the DSM which describe buildings. The second task is the reconstruction of buildings for which we apply parametric and prismatic building models. The main focus is on the detection, namely on the use of height and differential geometric infor...
متن کاملBuilding Change Detection Based on Object Extraction in Dense Urban Areas
This study presents a novel approach for building change detection from digital surface models (DSMs), which are generated from the images acquired by a multi-line digital airborne sensor ADS40. Our approach is based on building extraction, which is one of the most challenging research fields. A scheme is proposed that allows efficient integration of a local surface normal angle transform (LSNA...

متن کاملAutomatic Building Detection and Delineation from High Resolution Space Images Using Model-based Approach
An approach was developed for updating the buildings of an existing vector database from high resolution space images by using spectral values, Digital Elevation Models (DEM) and model-based extraction techniques. First, the building areas are detected using image classification and normalized Digital Surface Model (nDSM). Those areas other than the buildings are excluded from further processin...
