Building extraction using dual-aspect high resolution SAR images

Interpretation of SAR image in urban area is far from solved with the increase of spatial resolution, and building extraction in SAR image has remained as a tough work. Typically, the outlines of buildings are usually not complete, and the geometric distortions further complicate the appearances of buildings in high resolution SAR images. Thus, in this paper, a strategy based on dual-aspect high resolution SAR images was proposed to extract complete footprint of buildings in urban area. Experiments prove that dual-aspect SAR images, especially with high resolution, are very useful for building extraction in urban areas.
