Building extraction from high resolution SAR imagery in urban areas

In this paper, the textural characteristics of the buildings were quantified by using two texture descriptors, namely, Square Root Pair Difference (SRPD) and Gi*. Then, a novel method, based on SRPD and Gi*, to extract building areas in urban areas from very high resolution SAR images is presented. The results showed that this method has the ability to differentiate buildings from the complicated features in urban areas, which can be employed for land mapping and provides support for relief operations.
