Earthquake damage detection for building by fusion of the high-resolution optical and SAR images based on the correlation coefficient for the 2008 Wenchuan earthquake

Some well known technics of building boundary extraction have already been proposed in the fields of optical or SAR imagery in previous papers and have proved to provide efficient results for normal structure building. But the building damaged by the earthquake generally has anomalous shape and texture which make it hard to perform the anticipant result. In this paper, we propose to fuse the high-resolution optical and SAR images based on the correlation coefficient in order to detect the earthquake damage for building as follow steps:
