The Impulse Outlier Suppression Techniques Using ROAD and VMF for Color Portraits

Due to the immense necessity of admirable electronic paintings, which must be restored from an impulsive outlier, during the last two decades, there are immense researches and developments on outlier restoration algorithms. As a results, this paper proposes the alternative impulsive noise restoration algorithm based on ROAD (Rank-Ordered Absolute Differences) and VMF (Vector Median Filter) for color electronic paintings under an impulsive noise. From theoretical point of view, ROAD is one of the superior outlier allocating and VMF is one of the superior outlier restoration for color electronic painting. By exhaustive experiment, the proposed outlier restoration algorithm is implemented on many standard electronic paintings, which are undermined by an impulsive outlier with many distribution quantities. Moreover, the state-of-art outlier restoration algorithms, for instant SMF (Standard Median Filter) and VMF (Vector Median Filter), are comparatively experimented for exposing the efficiency of the proposed algorithm.
