* This filter creates a labeled image that separates the input
* image into various classes. The filter
* computes the thresholds using the OtsuMultipleThresholdsCalculator and
* applies those thesholds to the input image using the
* ThresholdLabelerImageFilter. The NumberOfHistogramBins and
* NumberOfThresholds can be set
* for the Calculator. The LabelOffset can be set
* for the ThresholdLabelerImageFilter.
