Change extraction of building is needed to revise building data effectively. Many change detection algorithms use height difference analysis using temporal data such as LIDAR. However, remarkable changes of buildings cannot be detected in urban dense areas. On the other hand, building textures might change with higher possibility. However, the change cannot be detected due to influences of shad...

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...

InSAR data are used to recognise large industrial building complexes. Such buildings often show salient regular patterns of strong scatterers on their roofs. A previous segmentation which uses the intensity, height and coherence information extracts building cues. Strong scatterers are filtered by a spot detector and localised by a cluster formation. Strong scatterers are grouped in rows by a p...

In this paper, we present an automatic building extraction method based on an object approach from Digital Elevation Models. First, a rough approximation of the building footprints is realized by a method based on marked point processes: the building footprints are modeled by rectangle layouts. Then, these rectangular footprints are regularized by improving the connection between the neighborin...

the structural slenderness ration (height/ with) is one of the title that can be discussed in quake design of building. but unfortunately, in  iranian code isn’t mention this mater.in this article, bending and bracying structures system are chosen with slenderness ratio 2 upto 6. (11, 17, 23, 29, 35 stage).all of structure are analysed and designed in linear method, then analysed in unlinear me...

The point densities obtained by airborne laser scanner systems are increasing rapidly. When used for the 3D reconstruction of buildings the increasing amounts of points contain more and more information about the shape of buildings. Therefore methods for 3D reconstruction can be more data driven and need less specific object models. In this paper an approach is presented which is based on the d...

ISSN 2277-5056 | © 2012 Bonfring Abstract--In the present paper an investigation has been performed to examine the behavior of various alternative 3D models using ETABS software for reinforced concrete structure with central core wall with outrigger and without outrigger by varying the relative flexural rigidity from 0.25 to 2.0 with step of 0.25. Also the position of outrigger has been varied ...

A new approach for determining building boundaries through automatic processing of light detection and ranging (LIDAR) data is presented. In general, LIDAR data is processed and interpolated into grayscale images with pixel values corresponding to height measurements. In a recent work, a progressive morphological filter was used to separate ground from non-ground measurements. Further separatio...

Abstract Seismic isolation has been widely accepted as one of the techniques that can be used to protect structures during earthquake ground motions. However, some challenges still exist such optimal control excessive isolator shear strains imposed by The main purpose this study was assess effects building height variation and motion type on performance seismic using lead core rubber bearing (L...
