Abstract

Good polarization SAR speckle reduction effect is very helpful to follow-up treatment for such as Polarization SAR image classification and interpretation. Based on analysis of the existing polarization SAR image filtering algorithm, an algorithm of PolSAR speckle reduction was proposed to maintain the relative phase information with SAR image speckle reduction of the total variation of partial differential equations (TV-PDE). First, three polarization combinations which could be represented by three color channels were got from Polarization SAR data with Pauli decomposition. Then, the color channels were operated with TV-PDE speckle reduction algorithm. The experiment results showed that the algorithm is effective and of good performance in the filtering and edge preservation. Comparison was made with other speckle filtering algorithms taking speckle index as the evaluation criteria.
