* \class MomentsThresholdImageFilter
* \brief Threshold an image using the Moments Threshold
*
* This filter creates a binary thresholded image that separates an
* image into foreground and background components. The filter
* computes the threshold using the MomentsThresholdCalculator and
* applies that threshold to the input image using the
* BinaryThresholdImageFilter.
