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: `stream` - displays to terminal
            immediately, `allatonce` - waits till command is finished to display
            output, `file` - writes output to file, `none` - output is ignored

    [Optional]
    args: (a string)
            Additional parameters to the command
            flag: %s
    background: (an integer)
            The value associated with the background (not object)
            flag: --background %d
    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)
            flag: --foreground %d
    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
            flag: %s, position: -2
    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.
            flag: --majorityThreshold %d
    outputVolume: (a boolean or a file name)
            Output filtered
            flag: %s, position: -1
    radius: (an integer)
            The radius of a hole to be filled
            flag: --radius %s

Outputs:

    outputVolume: (an existing file name)
            Output filtered
