Abstract

A wavelet-based algorithm for polarimetric SAR imagery segmentation is developed. It utilizes the property that under wavelet transform correlation is very weak among the intensity HH, HV, VV channels as well as among the subimages in the same channel to form the effective feature vector for parametric segmentation. The statistical separability measures including the Bhattacharyya distance and a separability inhomogeneity function (SIF) are employed to extract the most effective feature vector in the sense of minimizing SIF. The algorithm is applied to the supervised segmentation of the polarimetric SAR imagery of San Francisco Bay area. It shows a good segmentation performance and a significant computational reduction. The segmentation result is also favorably compared with that of Gaussian modeling or mixture Gaussian modeling under non-feature extraction representation.
