TEXTURE ANALYSIS OF POLARIMETRIC SAR

The Wavelet Polarization Signature (WASP) is a recently introduced formalism for analyzing the dependences of texture measures, in SAR imagery, afforded by wavelet frames on scale and polarization state. Based on a previously published theoretical approach, two experiments are reported where wavelet WASP analysis is applied to SAR observations of natural targets, both in the land and marine domains. The objective is to assess the potential usefulness of the technique in different thematic contexts and to validate experimentally the effects predicted by theory. Analysis conducted so far indicates that texture measures based on wavelet frames can be an effective vehicle to characterize the spatial statistics of SAR observations in the combined space-scale-polarization domain. 1
