Module: Skeleton Image To Graph

Description:

Converts a skeleton to a graph structure called HxSkeleton.

Left: Initial skeleton. Right: resulting graph structure (drawn with Draw_Skeleton ).

Connections:

Image

[required]
The input image, of type HxUniformScalarField3 comes in through this port.

Ports:

Threshold

Used to define, along with the comparison operator, which pixels are in the skeleton.

Comparison

Used to define how the threshold value is used for defining the skeleton.

Connectivity

Specifies the connectivity, either 6- or 18- or 26-connectivity.

Illustration of the different connectivities in 3D. (a): 6-, (b): 18-, and (c): 26-connectivity (in case you didn't figure it out, n-connectivity means n pixels in the neighbourhood).

Boundary_condition

Defines whether branches on the left side are connected to the right side.

Action button

Push the button to start the computation.

Commands:

Additional options can be accessed when typing in the console Skeleton_Image_To_Graph COMMAND_NAME. Typing the command again usually reverts back to original settings.

`verbose`

Displays timing and other information after the computation. Retype to hide info.

`create`

Runs the computation. Returns the name of the output, so it can be used in a script, such as set RESULT [Skeleton_Image_To_Graph create].
