How do you compare the frames? "Visually" or with some metric? Other in that thread are of fully different oppinion.

If it works for you, it's fine. I can only jugde from properties of the function byself: http://www.cambridgeincolour.com/tutoria...or-web.htm

Edit: In your case, make sure you "preblur" problematic images, to not emphasize those artifacts (unwanted edges) with the sharpening. Which needs an adaptive approach anyways.
