Errors

The equations as presented on this page make no sense. The Gaussian weighting function, for instance, is:

f(p,q)=e^{-{{\left\vert B(q)^{2}-B(p)^{2}\right\vert } \over h^{2}}}

but the $^{2}$ should apply to the difference, not to each term. Also, B(p) can't be the average value surrounding the pixel! In NLM, you want co compare each pixel of the patch (reference position) to each pixel of patches in the neighborhood, and use their difference as a distance between the patches. The equations presented here do not match the ones of the paper and maybe these should be use directly rather than being rewritten incorrectly. This is currently a disaster for someone trying to implement NLM out of this page :) --2001:9E8:4544:E800:5CC:4341:9E77:2B70 (talk) 20:38, 8 September 2023 (UTC)[reply]

Combine similar nl-mean filter article

It seems that this article and Non-local means filter treats the same arguments... Should we put them together? --Llorenzi (talk) 17:24, 1 March 2012 (UTC)[reply]

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Non-local means. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Added archive https://web.archive.org/20111118001653/http://www.stanford.edu:80/~slansel/tutorial/summary.htm to http://www.stanford.edu/~slansel/tutorial/summary.htm

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
