A Comparison of Change Detection Statistics in POLSAR Images

Abstract

Change detection in polarimetric SAR (POLSAR) images is an important topic. Three statistics are compared on both simulated and real data for their efficacy in change detection. The three statistics are the contrast ratio, the ellipticity and the Bartlett test. The relative performance for these three test statistics on the two simulations is dramatically different. The results are illustrated and explained.
