smooth3 (MATLAB Function Reference)

Smooth 3-D data

Syntax

W = smooth3(V)
W = smooth3(V,'filter')
W = smooth3(V,'filter',size)
W = smooth3(V,'filter',size,sd)

Description

W = smooth3(V) smooths the input data V and returns the smoothed data in W.

W = smooth3(V,'filter') filter determines the convolution kernel and can be the strings gaussian or box (default).

W = smooth3(V,'filter',size) sets the size of the convolution kernel (default is [3 3 3]). If size is scalar, then size is interpreted as [size, size, size].

W = smooth3(V,'filter',size,sd) sets an attribute of the convolution kernel. When filter is gaussian, sd is the standard deviation (default is .65).

Examples

This example smooths some random 3-D data and then creates an isosurface with end caps.

data = rand(10,10,10);
data = smooth3(data,'box',5);
p1 = patch(isosurface(data,.5), ...
   'FaceColor','blue','EdgeColor','none');
p2 = patch(isocaps(data,.5), ...
    'FaceColor','interp','EdgeColor','none');
isonormals(data,p1)
