SAR Image Despeckling Method Based on Dual-tree Complex Wavelet

摘要：

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.
