More About »
StandardDeviationFilter
StandardDeviationFilter
filters
image
by replacing every value by the standard deviations of the values in its range
r
neighborhood.
StandardDeviationFilter
applies standard deviation filtering to an array of data.
MORE INFORMATION
StandardDeviationFilter
computes the standard deviation in
×
blocks centered on each pixel.
At the edges of an image,
StandardDeviationFilter
uses smaller neighborhoods.
StandardDeviationFilter
uses neighborhoods with vertical range
and horizontal range
.
StandardDeviationFilter
operates separately on each channel in an image.
In
StandardDeviationFilter
,
data
can be an array of any rank, and can contain symbolic as well as numerical entries.
