SEA OIL SPILL OBSERVATION BY MEANS OF ANALYSIS OF SPATIAL STATISTICS IN POLARIMETRIC SAR DATA USING WAVELET SIGNATURES

摘要

A multi-resolution analysis of polarimetric SAR data byrnmeans of wavelet frames is performed to characterizerndark areas in marine scenes. Polarimetric textures arernevaluated in the wavelet domain for differentrnpolarization states and spatial scales to characterize therndifferent dark areas. The adopted analytical tool is thernrecently developed Wavelet Polarimetric Signaturern(WASP) tool. Experiments on SIR-C/X-SAR C-bandrndata, related to oil spills, biogenic look-alikes and lowrnwind areas, showed the effectiveness of this analysis inrncharacterizing marine dark features.
