Building extraction based on stereo analysis of high-resolution SAR images taken from orthogonal aspect directions
In this paper high-resolution SAR images of an urban scene are analyzed in order to infer buildings and their heights from the different layover effects in perpendicular taken views. Due to the strong dependen...
