[edit] Added Definition and Properties

I just added some concrete information to the page. It is still not really satisfying me. Boostat 00:04, 2 March 2007 (UTC)

[edit] Use in Optics and Image Processing

While researching contrast measurement as used in autofocus, I ran across this journal article mentioning variograms:

Variogram-based method for contrast measurement, Luis Miguel Sanchez-Brea, Francisco Jose Torcal-Milla, and Eusebio Bernabeu, Applied Optics, Vol. 46, Issue 22, pp. 5027-5033

Perhaps this might be something to integrate either into Variogram or Autofocus. This is my first encounter with the variogram so I don't know how it's applied in an image processing context.

[edit] Add Chart

A graph of a variogram would ease its understanding (especially as far as efficiently conveying the range, sill, and nugget). I will try to put one up shortly, but if someone else already has a good example lying around (with range, sill, nugget marked), it would be copacetic if you could add it to this page. --Tekhnofiend (talk) 22:40, 10 March 2008 (UTC)
