SAR image denoising based on adaptive shrinkage factor
Xu Zhang · 2003
An efficient method based on adaptive shrinkage facto r to suppress the speckle noise in synthetic aperture radar (SAR) images, is pre sented. It combines wavelet coring and the joint use of scale and space consiste ncy. A shrinkage factor is assembled at each scale to modify the wavelet coeffic ient. Compared with the denoising methods based on Mallat decomposition and Wien er filter, the proposed technique produces a filter version of the original imag e with well preserved image details.
