Abstract
A new adaptive filtering algorithm in the undecimated wavelet domain based on several adjacent scales correlation is proposed in this paper. Moreover, the Gaussian Markov random field (GMRF) model is used to characterize the inner-scale contextual dependence of wavelet coefficients. In the end, both the simulated speckle images and the real SAR images are used to validate the performance of our new algorithm.
