We demonstrate a brand-new method to sharpen a color image by using the integral mask-filtering technique. The high and low frequency messages between the target pixel and its neighbors are transferred by nonlinear functions. Both intensity and saturation factors of the HSV color system are taken into account. The obtained final image has clearer fine characteristics along with much less overshooting.
