[Insight-users] Cross Correlation Coefficient

[Martin Urschler]

I would suggest to look at the NormalizedCorrelationImageToImageMetric. 
You can use the GetValue method to compute the normalized cross 
correlation. Simply invoke it with the IdentityTransform.
If it doesn't do what you want you can at least look at the 
implementation of this class and write your own 
CrossCorrelationImageFunction.
