Speckle filtering in radar polarimetric images by wavelet transform in complex domain

Abstract

Polarimetric SAR images are disturbed by an inherent noise called "speckle" having multiplicative properties. This noise is undesirable, and its treatment in the case of polarimetric SAR images is difficult because of its complicated modelling. To reduce its level of disturbance, a polarimetric filtering is necessary to improve the image quality, with… (More)
