Abstract

In this paper we introduce a method that allows automatic extraction of planar features from tomographic SAR data. Our approach takes advantage of the spatial connectivity of pixels from tomographic height maps in order to retrieve planar patches from noise corrupted complex scenes. We demonstrate how our method outperforms the well-known RANSAC algorithm over synthetic and experimental data.
