BUILT-IN MATHEMATICA SYMBOL
HarmonicMeanFilter[image, r]
filters image by replacing every value by the harmonic mean of the values in its range-r neighborhood.
HarmonicMeanFilter[data, r]
applies harmonic mean filtering to an array of data.
Details
- HarmonicMeanFilter[image, r] computes the harmonic mean of the values in
blocks centered on each pixel. - At the edges of an image, HarmonicMeanFilter uses smaller neighborhoods.
- HarmonicMeanFilter works with 3D as well as 2D images, and also with data arrays of any rank.
- HarmonicMeanFilter[image, {rrow, rcol}] uses range
in height, and 
in width. - HarmonicMeanFilter[image, {rslice, rrow, rcol}] uses range
in height, 
in depth, and 
in width. - HarmonicMeanFilter operates separately on each channel in an image.
