SAR speckle denoising using iterative filter
Mohamed Yahia, Tej-Albaha Hamrouni, Riadh Abdelfattah · 2017
In this paper, we exploited the minimum mean square error (MMSE) estimator to define an iterative synthetic aperture radar (SAR) speckle filtering process. Hence, by optimally choosing the window size and the number of iterations, the proposed iterative filter outperforms classical MMSE speckle filtering techniques such as the improved Lee filter in terms of speckle reduction and spatial detail preservation.
