SAR image despeckling method based on dual-tree complex wavelet
Shuang Wang, Jiao Zhou, Jun Li, Hongxiao Feng · 2011
We propose a despeckling method based on dual-tree complex wavelet transform (DTCWT) for SAR image. The Gaussian model is used to model the non-logarithmic additive noise of the local isotropic region. Shrinkage function is obtained with maximum a posteriori estimation.
