Images de radar à Ouverture synthétique : transformée de Mellin et multirésolution

Synthetic Aperture Radar (SAR) provides characteristic images speckle of which make them harder to analyse. Speckle can be modeled by an almost unknown method : the Mellin convolution, based on the Mellin transform. By this way, the texture of SAR images can be easily characterized. A multiresolution approach yields statistical models which can be better analysed by this way.
