The picture in the article doesn't make any sense to me. Could someone add an explanation for it? --Brandon Dilbeck 07:48, 22 June 2007 (UTC)

I added some text, please help on what's the most confusing part of it to improve it further. --Berland 18:25, 22 June 2007 (UTC)
Actually, I think that did the trick; I understand it now. --Brandon Dilbeck 19:15, 22 June 2007 (UTC)
"Each coloured cell indicates the area in which all the points have the black point in the cell as their nearest black point"
Maybe I'm just tired, but this reads more like a tautology than an explanation. Clayhalliwell (talk) 19:18, 6 February 2008 (UTC)

Natural neighbor[edit]

What's the difference between "Nearest-neighbor" and "Natural neighbor" interpolation? Should these articles be combined, or at least reference one another? (talk) 22:43, 25 June 2009 (UTC)

They are completely different. Nearest neighbor produces a piecewise constant but discontinuous function by copying the function value from a single neighbor. Natural neighbor produces a function that is continuous, and smooth everywhere but at the data points, by combining the values of several nearby points (the points that would be adjacent in the Delaunay triangulation if the point at which the function is being interpolated were added to the set of data points). —David Eppstein (talk) 05:46, 26 June 2009 (UTC)

Missing Topics[edit]

  • Curse of dimensionality
  • Comparison to other smoothing functions
  • Uses
  • History

These are some topics I think are missing. I'll add some info when I can.--Diaa abdelmoneim (talk) 16:25, 9 February 2014 (UTC)
