“…The first method is called "change detection" and is based on identifying changes on an object at different times (Singh, 1989). Several change detection techniques were employed in previous works for detecting changes in buildings from pre-and post-disaster images (Brunner, et al, 2010, Myint, et al, 2008, Radhika, et al, 2013, Turker and Cetinkaya, 2005, Womble, et al, 2007. For example, tornado affected areas were identified using remote-sensing images and three change detection approaches, including the Principal Component Analysis (PCA), Image Differencing, and Object-oriented Classification (Myint, et al, 2008).…”
