Abstract

In InSAR interferogram processing, phase filtering is an extremely critical step, and traditional filtering methods have defects such as difficulty in identifying edge information, and easy confusion of noise and mutation signals. In order to solve the above problems, we propose a filtering method based on the Steerable Pyramid. The results of applying this method to the interferogram are compared with five traditional filtering methods, and we found that it not only performs well in the visual result of the filtered interferogram, but also shows superiority in various filtering quantitative index evaluation.
