Abstract
In this paper we present the Wavelet Domain Vector Median M-type L-filter (WDVMML) for the removal of impulsive and speckle noise in color image processing applications. The proposed filter uses the robust RM-estimator in the filtering scheme of L-filter. We adapt the RM L-filter to work in wavelet domain by use the Daubichies wavelet dB4. Simulation results have demonstrated that the proposed filter consistently outperforms other filters by balancing the tradeoff between noise suppression and detail preservation.
