“…The result of this work exhibits the buildings obtained through a totally automatic way. In this we made possible to view the significant progress as well as the limitations in this topic (Gamanya, Maeyer & Dapper, 2009). Final products were confirmed in field and we evidenced the last technologies in image segmentation, mixed with point clouds LIDAR and the integration of the different algorithms of class assignation that allow us to automatically obtain the buildings of the working area with a 97.2% 2 trust.…”

“…Studies using satellite images (Al-Khudhairy et al, 2005;McDermid et al, 2008;Niemeyer et al, 2008;Hofmann et al, 2008;Gamanya et al, 2009;Bouziani et al, 2010;Huang et al, 2014) did not use DSM for CD. CD was based solely on the analysis of image data.…”

“…This study is based on (Hofmann, 2001) which is dedicated to the same topic, but uses the IKONOS images. The hierarchical image segmentation approach of multitemporal Landsat TM and ETM images was adopted by (Gamanya et al, 2009). The aim of this study is to perform CD by using fuzzy logic classification implemented in Definiens Professional software.…”

“…producing salt-paper results due to high spectral diversity, high time processing and inability to interpret image due to weakness of pixel information) (Chen, Hay et al 2012). Therefore, with the development of objectbased techniques, the unit of image analysis changed from pixel to object (Blaschke 2010) and the limitations of pixel-based techniques have been solved (Hall and Hay 2003, Laliberte, Rango et al 2004, Blaschke 2005, Desclée, Bogaert et al 2006, Bontemps, Bogaert et al 2008, Gamanya, De Maeyer et al 2009). In object-based techniques, homogeneous image objects have more signal to noise ratio rather than image pixels.…”
