抄録(英) | In this paper, statistical approaches of K-distribution and Getis statistics are exploited to assess building damage caused by Wenchuan earthquake in 2008. To verify the proposed methods, analysis is firstly done on simulated images with bright squares as building objects in random background. Both approaches show high accuracy in assessing the simulated damaged buildings. These statistics are then applied to two single-polarization ALOS-PALSAR images over Beichuan city, which were acquired before and after the Wenchuan Earthquake. Results of K-distribution and Getis statistics show that the damage level might reach 93% and 81%, respectively. |
