“…The coherent target decomposition algorithms include the Pauli decomposition, the sphere-diplane-helix (SDH) decomposition [5], the symmetric scattering characterization method (SSCM) [6], Cameron decomposition [7], Yamaguchi Fourcomponent scattering power decomposition [8], General polarimetric model-based decomposition [9], [10], and some advances [11], [12]. The incoherent target decomposition algorithms include Huynen decomposition [13], Freeman-Durden decomposition [14], Yamguchi four-component decomposition [15], Cloude-Pottier decomposition [16], [17], and a number of approaches have been reported [18], [19], [20]. In addition to feature based on the polarization mechanism [21], [22], [23], [24], there are some traditional features of natural images, which have been utilized to analyze PolSAR image, such as color features [25], texture features [26], spatial relations [27], etc.…”
