Statistical modelling of Polarization Fraction for classification of PolSAR images using GMM
This paper presents a statistical model to classify the PolSAR image on the basis of Polarization Fraction (PF) of the backscattered wave. The basic principle behind PF, i.e., the relative power in the co-polarized and cross-polarized channel, is employed to distinguish between surface, double-bounce and volume scattering. We look to find the best fit model to the measured data by assuming it to be Gaussian distributed. A Radarsat-2 image of San Francisco is used to illustrate the results.
