COLOR IMAGE PROCESSING USING GENERALIZED WEIGHTED VECTOR FILTERS

Keywords: This paper focuses on generalized weighted vector filters which constitute a powerful filtering frameworkfor multichannel signalprocessing.The utilization of a generalized multichannel sigmoidal adaptation scheme allows to accommodate the filter parameters to varying signal and noise statistics. Experimental results indicate that the presented multichannel filters are capable of removing impulsive noise present in color images and simultaneously they preserve color and structural information.
