Is there a way to perform an unsharp mask within the intel library? It seems that this is the best way to achieve a controled level of sharpen to an image. When reviewing how an unsharp mask works it looks like it is a low pass blur along with a convolution filter subtracted from it. Anyone been able to pull this off properly?
