``Ultimate_Erosion'' - ultimate erosion

VFX name:

iUltimateErode

IMPROMPTU Equivalent:

Ultimate_Erosion

purpose:

Perform an ultimate erosion on an input volume.

The voxels in the final result are labelled. The label of a voxel refers to the number of erosions (under the connectivity conditions specified by the parameter ``option'') needed to delete the voxel. For example, if a voxel is labelled 3 and the parameter ``option = 3-D_26-connected'', then it takes 3 3x3x3 erosions to have the voxel be eroded away.

input:

An 8-bit volume.

output:

An 8-bit volume.

parameters:

Default parameters menu is

option = 3-D_26-connected

The parameter ``option'' specifies the type of morphological operations done during the ultimate erosion. The options are

1.

3-D_26-connected - do 3x3x3 operations

2.

3-D_6-connected - do 6-connected operations

3.

2-D_8-connected - do 3x3x1 operations

4.

2-D_4-connected - do 4-connected (x-y plane) operations

comments:

1.

This operation can be slow, since a large number of operations may be needed to erode everything away.
