The theoretical foundations of genetic algorithms (GA) rest on the shoulders of the Schema Theorem, which states that the building blocks, highly t compact subsets of the chromosome, are more likely to survive from one generation to the next. The theory of genetic programming (GP) is tenuous , borrowing heavily from that of GA. As the GP can be considered to be a GA operating on a tree structur...

This study aims to extract automatically building roof planes from airborne LIDAR data applying an extended 3D Randomized Hough Transform (RHT). The proposed methodology consists of three main steps, namely detection of building points, plane detection and refinement. For the detection of the building points, the vegetative areas are first segmented from the scene content and the bare earth is ...

being very dynamic, natural and artificial land features are changing somewhat rapidly in over lifetime. it is important that such changes be inventoried accurately so that the physical and human processes at work can be more fully understood. change detection is a technique used in remote sensing to determine the changes in a particular object of study between two or more time periods. this re...

We investigate the potential of combined features of aerial images and high-resolution interferometric SAR (InSAR) data for building detection in urban areas. It is shown that completeness and correctness may be increased if we integrate both InSAR double-bounce lines and 3D lines of stereo data in addition to building hints of a single optical orthophoto. In order to exploit context informatio...

A new method for building change detection from Digital Surface Models (DSM) and multi-spectral images is presented. The DSM can be generated from Airborne Laserscanner (ALS) data or by image matching techniques. From the multi-spectral image, the Normalised Difference Vegetation Index (NDVI) is computed and used in the change detection process. The workflow of the method consists of two stages...

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...

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...

The elevation information is not considered in the traditional building change detection methods. This paper presents an algorithm of combining LiDAR data and ortho image for 3D building change detection. The advantages of the proposed approach lie in the fusion of the height and spectral information by thematic segmentation. Furthermore, the proposed method also combines the advantages of pixe...

Laser scanning is a new technology for obtaining Digital Surface Models (DSM) of the earth surface. It is fast method for sampling the earth surface with a high density and high point accuracy. In this paper a procedure for building detection and roof extraction from the DSM is presented. The procedure starts by re-sampling elevation as obtained by laser scanning into regular grid. The core par...
