Polarimetric-scattering-similarity in PolSAR denoising

In polarimetric filters, the adjacent pixels in the same neighborhood are regarded as possessing similar scattering mechanism, and these pixels in the continuous window are usually selected to do the averaging process when filtering the central pixel. Considering the different similarity between each neighbor pixel and the central pixel, the averaging process is given by a new definition and used in the polarimetric filter. Because polarimetric scattering similarity (PSS) is used as a weight here, we call it PBW (PSS-based weight) in simple. Employing the PBW in the multi-look-like filters, we can get several improved results in polarimetric filtering by comparison experiments.
