The Use of Non Local Filters in Polsar Applications

In this study, the capability of polarimetric Non Local Filters (NLFs) for speckle reduction in POLarimetric Synthetic Aperture Radar (POLSAR) measurements is investigated. Among different POLSAR applications where speckle filtering is a key point, shoreline extraction is here addressed. A C-band Radarsat-2 POLSAR scene is considered where the shoreline extraction procedure proposed in [5] is applied. The effects of different POLSAR speckle filters, including NLFs, are analyzed.
