Talk:Resampling

DSP vs. stats
I can flesh out an article on resampling as in DSP. Resampling as in statistics I don't know much about, but I bet it will end up wanting to be a separate article. Well, how about I get a DSP article up and then worry about splitting. Eub 04:39, 18 July 2005 (UTC)

Article split?
I am open to splitting this article into Resampling (audio) and Resampling (bitmap) (or something similar). I find a little too many articles on image scaling/image resampling (Image scaling, Subsampling, Pixel art scaling algorithms at least), some of them should be merged and that would be easier if image resampling/image scaling/bitmap resampling could be its own article. --Berland (talk) 05:48, 21 February 2008 (UTC)
 * Or perhaps let Image scaling cover Resampling (bitmap). --Berland (talk) 18:30, 9 August 2008 (UTC)

I totally agree with an article split. In general, I believe that "resampling" methods need to be distinguished from "interpolation" methods. Interpolation should be defined in the function space to be a little more general. Resampling should specify the cases where the function is a constant. I would personally keep audio and images together since the equations are the same with the note difference that one applies the algorithms in 2 dimensions where as the other does so in one. They are both sampling cases. I would also suggest that this happens to the BiCubic interpolation. Ti chris (talk) 08:51, 9 June 2008 (UTC)
 * Resampling in audio and image are certainly sort the same thing, but I think the dimensionality difference is enough for it to warrant two different articles on Wikipedia. --Berland (talk) 19:32, 16 June 2008 (UTC)

Yes, split. Berland gave some very good reasons already. Extensive treatments of Resampling (audio) and Resampling (image processing) would be more natural if they were in separate articles. Resampling of different signals are motivated, and the choice of the methods guided, by different reasons. The mathematical framework underlying the basic methods is the same for both, but I don't think that justifies keeping them together, given the reasons to split. A more general treatment could be given in Resampling (signal processing) with links to application-specific "main article" resampling pages. Olli Niemitalo (talk) 13:03, 30 December 2008 (UTC)
