> description: A simple region growing segmentation algorithm based on intensity statistics. To create a list of fiducials (Seeds) for this algorithm, click on the tool bar icon of an arrow pointing to a starburst fiducial to enter the ‘place a new object mode’ and then use the fiducials module. This module uses the Slicer Command Line Interface (CLI) and the ITK filters CurvatureFlowImageFilter and ConfidenceConnectedImageFilter.

> argsa unicode string

>   Additional parameters to the command. Maps to a command-line argument: `%s`.

> environa dictionary with keys which are a bytes or None or a value of class ‘str’ and with values which are a bytes or None or a value of class ‘str’

>   Environment variables. (Nipype default value: `{}`)

> inputVolumea pathlike object or string representing an existing file

>   Input volume to be filtered. Maps to a command-line argument: `%s` (position: -2).

> iterationsan integer (int or long)

>   Number of iterations of region growing. Maps to a command-line argument: `--iterations %d`.

> labelvaluean integer (int or long)

>   The integer value (0-255) to use for the segmentation results. This will determine the color of the segmentation that will be generated by the Region growing algorithm. Maps to a command-line argument: `--labelvalue %d`.

> multipliera float

>   Number of standard deviations to include in intensity model. Maps to a command-line argument: `--multiplier %f`.

> neighborhoodan integer (int or long)

>   The radius of the neighborhood over which to calculate intensity model. Maps to a command-line argument: `--neighborhood %d`.

> outputVolumea boolean or a pathlike object or string representing a file

>   Output filtered. Maps to a command-line argument: `%s` (position: -1).

> seeda list of items which are a list of from 3 to 3 items which are a float

>   Seed point(s) for region growing. Maps to a command-line argument: `--seed %s...`.

> smoothingIterationsan integer (int or long)

>   Number of smoothing iterations. Maps to a command-line argument: `--smoothingIterations %d`.

> timestepa float

>   Timestep for curvature flow. Maps to a command-line argument: `--timestep %f`.

> outputVolumea pathlike object or string representing an existing file

>   Output filtered.
