“…The methods lend themselves to seek greater accuracy by further analysis, building on thresholding and region-growing techniques by, for example, Yu and Clausi (2007);Matgen et al (2011);Galland et al (2009) and Silveira and Heleno (2009). Other successful segmentation methods for SAR images involving texture and shape (van der Werff and van der Meer, 2007), active contours (Ben Ayed et al, 2005;Chakraborty et al, 2009;Fu et al, 2008) and multi-objective algorithms (Collins and Kopp, 2008) may be suitable. However, it is felt that the basic premise of same-track image differencing (to mitigate incidence-angle effects and ambiguous low-backscatter response due to absorption), coupled with a robust region-growing segmentation technique (e.g.…”
