Comment:
͏ Some low-effort testing seems to indicate the algorithm being able to
give output similar (in some cases identical...) to [/wiki/denoise#nlmeans
͏"nlmeans"].
͏ This commit should be a good start point: (as copy)
͏ https://trac.ffmpeg.org/ticket/4910#comment:16
͏ .
͏ The algorithm is essentially NLM without the patch matching
weighting.
͏ (and optimized to avoid pointless work)

͏ ... , the filter badly needs some performance improvements.
͏ Also, any suggestion on how not to make it spend 80% of the time in
"nlmeans_slice" welcome. ]
<!^> Never considered to drop the patch matching outright..?
