Abstract :
The authors present a texture-base approach to the classification of SAR images recorded over urban environments. In particular, they explore the use of some co-occurrence measures and the wavelet frame decomposition, to investigate if there is an advantage, and where, in using these tools. They found that the correct classification rates are only partially increased by using these additional information, with a slight preference for texture analysis through the co-occurence matrix. These considerations are validated by analyzing polarimetric SAR images recorded over Los Angeles by the AIRSAR sensor
