The preservation of structural information and polarimetric scattering properties is the major obstacle in despeckling for Polarimetric Synthetic Aperture Radar(PolSAR)images.Speckle reduction for PolSAR images using hybrid features similarity
to establish a method for extracting structural features by analyzing the structural feature and polarimetric information of PolSAR data
is proposed.The proposed method introduces structural characteristics as well as polarimetric scattering characteristics into the speckle reduction and in order to preserve them efficiently after filtering.The test results of real airborne SAR data show the effectiveness of the algorithm.
