> ImageMoments -> ImageMomentMetric

This class does not compute any sort of metric, so it should not be
called a Metric.  I suggest ImageMomentCalculator instead.  By
analogy, you would than also have ImageHistogramCalculator,
ImageFourierTransformCalculator, etc.

> (should be process object)

You could be right.  Is there any documentation that explains how to
construct and use process objects?  I find the code and comments in
itkProcessObject.* rather obscure.
