“…Figure 4f shows the k parameter for the last iteration. Although this parameter may not be regarded as the Equivalent Number of Looks (ENL) [29] it is related to it, in a similar manner to the multilook filtering window size. As explained before, the proposed method employs also the polarimetric locality to avoid mixing inhomogeneous samples of the image.…”

“…However, this measure was defined for single polarization SAR data and, when employing PolSAR data, different ENL values are obtained for each polarimetric channel. Some extensions to PolSAR data were proposed and analyzed in [29] based on the matrix trace moments (TM)L T M and on the Maximum Likelihood (ML) based on the Wishart distribution Equation (4)L M L :…”
