Filtragem não-local do ruído Speckle em imagens SAR com modelagem estatística dos coeficientes da Wavelet de Haar e distâncias estocásticas
(Universidade Federal de São Carlos, 2018-06-04)
Due to the coherent processing of synthetic aperture radar (SAR) systems, multiplicative
speckle noise arises providing a granular appearance in SAR images. This kind of noise
makes it difficult to analyse and interpret ...
