Simple Unsharp Mask Filter (Color and Grayscale)
----------
Parameters :
• Radius
Affects the size of the edges to be enhanced or how wide the edge rims become, so a smaller radius enhances smaller-scale detail.
• Amount
Controls the magnitude of each overshoot (how much darker and how much lighter the edge borders become).
• Threshold
Controls the minimum brightness change that will be sharpened or how far apart adjacent tonal values have to be before the filter does anything.

I have just few seconds ago learned about the Lenna photo. Now I see it everywhere like the utah teapot. Anyway, pretty useful.
