The present work aims to introduce an efficient set of high spatial resolution (HSR) images in order to more fairly evaluate building detection algorithms. The introduced images are chosen from two recent HSR sensors (QuickBird and GeoEye-1) and based on several challenges of urban areas encountered in building detection such as diversity in building density, building dissociation, building sha...

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...

extended abstract 1. introduction from about the 1950s, extraordinary growth of cities and increase of urban population have led to excessive growth of settlements in cities (muhallab taha, 2001(. this growth caused an unprecedented rise in land prices (zaheri & pour- mohammadi, 2006). land is an essential element in urban expansion and development (vander molen, 2002). therefore, quality and q...
