smooth3

Smooth 3-D data.

📝Syntax

W = smooth3(V)
W = smooth3(V, method)
W = smooth3(V, method, windowSize)
W = smooth3(V, method, windowSize, sd)

📥Input Arguments

Parameter	Description
V	Real numeric or logical 3-D volume data.
method	Smoothing method: 'box' or 'gaussian'. The default is 'box'.
windowSize	Positive odd integer scalar or three-element vector. The default is [3 3 3].
sd	Positive standard deviation for the gaussian method. The default is 0.65.

📤Output Arguments

Parameter	Description
W	Smoothed double array with the same size as V.

📄Description

smooth3 smooths volumetric data with a separable 3-D box or gaussian kernel and replicated boundary values.

💡Examples

Smooth a small volume with a gaussian kernel.

V = rand(10, 10, 10);
W = smooth3(V, 'gaussian', 5);
