Wraps command **OtsuThresholdImageFilter **

title: Otsu Threshold Image Filter

category: Legacy.Filtering

description: This filter creates a binary thresholded image that separates an image into foreground and background components. The filter calculates the optimum threshold separating those two classes so that their combined spread (intra-class variance) is minimal (see http://en.wikipedia.org/wiki/Otsu%27s_method).  Then the filter applies that threshold to the input image using the itkBinaryThresholdImageFilter. The numberOfHistogram bins can be set for the Otsu Calculator. The insideValue and outsideValue can be set for the BinaryThresholdImageFilter.  The filter produces a labeled volume.

Inputs::

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

        [Optional]
        args: (a string)
                Additional parameters to the command
        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
        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
        insideValue: (an integer)
                The value assigned to pixels that are inside the computed threshold
        numberOfBins: (an integer)
                This is an advanced parameter. The number of bins in the histogram used to model the
                probability mass function of the two intensity distributions. Small numbers of bins may
                result in a more conservative threshold. The default should suffice for most
                applications. Experimentation is the only way to see the effect of varying this
                parameter.
        outputVolume: (a boolean or a file name)
                Output filtered
        outsideValue: (an integer)
                The value assigned to pixels that are outside the computed threshold

Outputs::

        outputVolume: (an existing file name)
                Output filtered

Wraps command **ResampleScalarVolume **

title: Resample Scalar Volume

category: Legacy.Filtering

description: Resampling an image is an important task in image analysis. It is especially important in the frame of image registration. This module implements image resampling through the use of itk Transforms. This module uses an Identity Transform. The resampling is controlled by the Output Spacing. "Resampling" is performed in space coordinates, not pixel/grid coordinates. It is quite important to ensure that image spacing is properly set on the images involved. The interpolator is required since the mapping from one space to the other will often require evaluation of the intensity of the image at non-grid positions. Several interpolators are available: linear, nearest neighbor, bspline and five flavors of sinc. The sinc interpolators, although more precise, are much slower than the linear and nearest neighbor interpolator. To resample label volumnes, nearest neighbor interpolation should be used exclusively.
