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