Abstract
Speckle reduction and enhancement of synthetic aperture radar (SAR) images with multiple wavelets (multiwavelets) are proposed and investigated. The multiwavelet transformations are useful for speckle reduction through its subband-images and the speckle reduction is obtained by thresholding the subband-image coefficients of the digitized SAR images. Two methods are investigated, both of them are non-linear methods and are based on soft and hard thresholding the multiwavelet coefficients for logarithmically transformed SAR image data. The proposed methods shows great promise for speckle removal and hence provides good detection performance for SAR based recognition.
