``Cue-based_region_grow'' - segment a volume using user defined cues

VFX name:

iCueRegionGrow

IMPROMPTU Equivalent:

Cue-based_region_grow

purpose:

Segment a volume using user defined biopsy cues. A region is grown based upon the cues. The first step calculates Mean (mue) and Standard deviation (sigma) of the voxels in the biopsy. Adjacent voxels to the biopsy are grown if the following two conditions exist:

1.

$\vert v(x,y,z) - mue\vert \leq a.sigma$

2.

v(x,y,z) is connected to grown region

The Inclusionary cue allows the user to specify areas of the original image where region grower is allowed to grow. This corresponds to user identifying boundaries which enclose the desired object.

input:

An 8-bit grayscale volume. Coded 8-bit cue images.

output:

An 8-bit grayscale volume, containing only the bright, connected objects.

parameters:

Default parameters menu is

cue_filename_prefix = cam
Num_regions = 1
cue_types = Biopsy_and_Inclusionary

The parameter ``Cue Types'' should be toggled to desired cue types.

None.
