Fig. 10.2 Unsupervised change detection in multitemporal high resolution data. Upper row :The
raw QuickBird image, acquired in 2007, in RGB321 ( left ) and R432 ( right ). Middle row :Theraw
QuickBird image, acquired in 2009, in RGB321 ( left ) and R432 ( right ). Bottom row : The detected
changes (they are all new buildings), overlaid in the 2009 image, are shown with a red color .
Ground truth data are shown in green
