Statistical Analysis to Assess Building Damage In 2008 Wenchuan Earthquake from Multi-temporal SAR Images

摘要：

The statistical approaches,i.e.K-distribution and Getis statistics,are applied to ALOS PALSAR image for assessing the building damage caused by Wenchuan earthquake in 2008. As a proposed image analysis,a simulated image with random bright squares,as building objects,is firstly presented for analysis of the K-distribution and Getis statistics. Then,these statistics are applied to two ALOS PALSAR images acquired before and after the Wenchuan Earthquake to assess building damage level.Results of Kdistribution and Getis statistics show that the damage level might reach 93% and 81%,respectively.
