Abstract

A nonlocal InSAR filter is proposed that avoids the staircasing effect, which is especially troubling for DEM generation as it leads to terrace-like artifacts for hilly terrain. The sources of the staircasing effect for InSAR filtering are presented and the proposed filter is evaluated with simulations and test data, which show that the noise reduction and detail preservation are comparable to a state of the art nonlocal filter.
