[Insight-users] 3D registration using Normalized Mutual Information Metric

[Smriti Raghunathan]

Hi,
 I am trying to resgister 3D data sets using the
"ImageRegsitration8.cxx" algorithm in ITK. However, this code uses
"VersorRigid3DTransform", "itkVersorRigid3DTransformOptimizer" and
"itkMeanSquaresImageToImageMetric" as the registration metric.

I was trying to change parts of this code so that it used the same
transforms and optimizer but used the "Normalized Mutual Information
Metric" as the registration metric. However, when I build the project
and compile it, it gives me the following error when linking:

I am not sure what exactly this error is indicating... any kind of
help would be appreciated. If this is not helpful then i could send
the modified code.

thanks a lot
