[Insight-users] Normalisation of images necessary?

[Jef Vandemeulebroucke]

Hi, 

I am testing several mutual information metrics, plotting their behavior. 
Among the metrics are the two based on histograms:

MutualInformationHistogramImageToImageMetric
NormalizedMutualInformationHistogramImageToImageMetric

Do these metrics give better results when the images have been normalised, as it is for the Viola-Wells implementation of MI, or is this of no importance?

Thank you,

Jef
