[Insight-users] Scalar range of pixels

[Bill Lorensen]

To find the global min/max in an image you can run the filter:
itkMinimumMaximumImageFilter

Or if you don't need it in a pipeline, you can run itkMinimumMaximumCalculator.

The NumerciTraits report the largest and smallest possible values for
a given type, not the actual min and max in the image.
