Description

This module aims to suppress speckle in the SAR Sentinel-1 product (developed for GRD data) by using guided image filtering. The guided filter computes the filtered SAR output by considering the content of a guidance image (Sentinel-2 RGB image). Guided filter has a good edge-preserving property, while it suppresses speckle noise.
