Despeckling of SAR Image Using Generalized Guided Filter With Bayesian Nonlocal Means

Abstract

Due to the coherent nature of the scattering phenomenon, synthetic aperture radar (SAR) images are inherently contaminated by multiplicative speckle noise, which makes despeckling always a fundamental problem for SAR image processing. Motivated by the idea of the guided image filter, we propose an extended despeckling scheme named generalized guided filter… (More)
