Abstract
A COLOR IMAGE PROCESSING METHOD AND APPARATUS THEREOF ARE PROVIDED.THE COLOR IMAGE PROCESSING METHOD INCLUDES THE STEPS OF (A) SORTING IMAGE PIXELS ACCORDING TO THE COLOR DISTANCE BETWEEN THE IMAGE PIXELS AND A CENTRAL PIXEL (104), (B) GROUPING THE SORTED PIXELS INTO GROUPS IN WHICH THE DIFFERENCE IN THE INTRAGROUP COLOR DISTANCE IS MINIMUM AND THE DIFFERENCE IN THE INTERGROUP COLOR DIFFERENCE IS MAXIMUM (106), AND (C) PERFORMING FILTERING BY REPLACING A CENTRAL PIXEL VALUE WITH A PREDETERMINED PIXEL VALUE DETERMINED BY PIXEL VALUES OF PIXELS IN THE GROUPS. THE COLOR IMAGE PROCESSING METHOD CAN REDUCE THE GENERATION OF EDGE BLURRING OF THE IMAGE IN REMOVING IMPULSE NOISE FROM AN IMAGE AND FILTERING THE SAME.(FIG.1A)
