[Insight-users] Modifying 3D rigid registration to use Mutual Information

[William Whartenby]

I am trying to modify the 3D rigid registration (as given in Examples, ImageRegistration8) to use Mutual information. I have tried changing the 
itkMeanSquaresImageToImageMetric.h include 
and 
typedef itk::MeanSquaresImageToImageMetric< 
                                  FixedImageType, 
                                    MovingImageType >    MetricType;
to both MattesMutualInformation and MutualInformation,
and the code builds, but seems to give wrong results. In one test case, the MattesMutual will not even do one iteration, just reports a fit (where the two images aren't registered)
  Does anyone have a good Mutual Information 3D rigid register code?
TYVM
Will
