 ## Description
 This example demonstrates two different blur methods (gaussian and normalized box) and a method to compute the focus amount of an image.
 Focus computation is useful for objects (and especially iris) detection.
-You can find more about focus computation on the appendix of *How Iris Recognition Works* by Paul Daugman (p.29).
