Wraps command **VotingBinaryHoleFillingImageFilter **

title: Voting Binary Hole Filling Image Filter

category: Filtering

description: Applies a voting operation in order to fill-in cavities. This can be used for smoothing contours and for filling holes in binary images. This technique is used frequently when segmenting complete organs that may have ducts or vasculature that may not have been included in the initial segmentation, e.g. lungs, kidneys, liver.

Inputs:

    [Mandatory]
    terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
            Control terminal output

    [Optional]
    args: (a string)
            Additional parameters to the command
    background: (an integer)
            The value associated with the background (not object)
    environ: (a dictionary with keys which are a value of type 'str' and with values which
             are a value of type 'str', nipype default value: {})
            Environment variables
    foreground: (an integer)
            The value associated with the foreground (object)
    ignore_exception: (a boolean, nipype default value: False)
            Print an error message instead of throwing an exception in case the interface fails to
            run
    inputVolume: (an existing file name)
            Input volume to be filtered
    majorityThreshold: (an integer)
            The number of pixels over 50% that will decide whether an OFF pixel will become ON or
            not. For example, if the neighborhood of a pixel has 124 pixels (excluding itself), the
            50% will be 62, and if you set a Majority threshold of 5, that means that the filter
            will require 67 or more neighbor pixels to be ON in order to switch the current OFF
            pixel to ON.
    outputVolume: (a boolean or a file name)
            Output filtered
    radius: (an integer)
            The radius of a hole to be filled

Outputs:

    outputVolume: (an existing file name)
            Output filtered
