In this paper we present the capability features of the RM L-filter in the wavelet domain for the removal of impulsive and multiplicative noise in image processing applications. The proposed filter uses the robust RM-estimator in the filtering scheme of L-filter. Extensive simulation results have demonstrated that the proposed filter consistently outperforms other filters by balancing the tradeoff between noise suppression and detail preservation.
