SAR Image Despeckling Based on Lapped Transform Domain Dual Local Wiener Filtering Framework

In this paper, a Synthetic Aperture Radar (SAR) image despeckling technique, based on lapped orthogonal transform (LOT) domain dual local Wiener filtering framework, is proposed. A logarithmic transformation is employed to convert the speckle contribution into additive noise. It is demonstrated that...
