[Insight-users] Question regarding itkNormalizedMutualInformationHistogramImageToImageMetric

[Kerstin Müller]

Hello everybody,

I want to compute the NMI with the
itkNormalizedMutualInformationHistogramImageToImageMetric, unfortunately I
do not have access to the book which is referenced that's why I'm posting
my question here. What's the range of this NMI? I thought it would be 0 - 1
but it's not, if I insert the same image the metric measure is 2 and if i
insert complete different images it is not 0.
Can someone comment on that?

Thank you very much,

Kerstin
