``Maximum'' -- local maximum

purpose:

Perform a local maximum operation on an input volume. The parameters ``x filter dim = '', etc., define the dimensions of the local operator used.

input:

An 8-bit grayscale volume.

output:

An 8-bit grayscale volume.

parameters:

Default parameters menu is

x filter dim = 3
y filter dim = 3
z filter dim = 3
option = rectilinear
no. of iterations = 1
input from vol # = 0
copy output to vol # = 0

The same connectivity options are available as for erosion and dilation (see parameter ``option = '').

comments:

 

1. If the input volume is binary-valued, then the local maximum gives the same output as a dilation.
2. This operation is moderately fast (similar to dilation).
