Abstract
In this paper, a color image sharpening algorithm is presented by using YCbCr color space representation and fractional differentiation operator. Because the quality of sharpened color image depends on the order of fractional differentiation, the modulation transfer function (MTF) in the human visual system (HVS) is employed to determine the best fractional order of differentiation. Various color images are used to show the effectiveness of the proposed color image sharpening method.
