Multichannel Median M-Type L Filter to Remove Impulsive Noise from Color Images

Abstract

In this paper, we present the multichannel median M-type L (MMML) -filter to remove impulsive noise from color images. The proposed technique uses the MM (median M-type) - estimator with simplest influence function in the L filtering algorithm and these are adapted to multichannel image processing applications. The results from known techniques are compared with the proposed method to demonstrate its performance in terms of noise suppression, detail preservation, and color retention.
