|
| Authors: | M. Mastriani and A. E. Giraldez
|
| Abstract: | In this paper, an efficient method for removing speckle (in wavelet domain) of unknown variance from Synthetic Aperture Radar (SAR) images is described. The method is based on a smoothing of the coefficients of the highest wavelet subbands. Specifically, we decompose the speckled SAR image into wavelet subbands, apply directional smoothing (DS) within each high subband, and reconstruct a SAR image from the modified detail coefficients. Despeckling results compare favourably with most methods in use at the moment.
