Abstract

To automatically detect and analyze the surface change in the urban area from multi-temporal SAR images, an algorithm of two-thresholds EM (Expectation Maximum) and MRF (Markov Random Field) is developed. Difference of the SAR images demonstrates variation of backscattering caused by the surface change over all image pixels. Two thresholds are obtained by… (More)
