ABSTRACT:
We demonstrate a
brand-new method to sharpen a color image by using an integral mask-filtering technique. The derivatives
between the target pixel and its neighbors are transferred by the cubic root
function instead of the traditional linear one. The obtained final image has clearer fine characteristics along with
much less overshooting.
