[Insight-users] Mutual information registration

[Yankam Njiwa Josiane Adrienne]

Hi together,

 

I would like to perform rigid registration of 3D data sets using mutual information as similarity criterion. I used ImageRegistration2.cxx and try to extend it to 3D. I have the following mesage error:

Description: itk::ERROR: MutualInformationImageToImageMetric(018844E8): All the
sampled point mapped to outside of the moving image


Do somebody where the problem could came from? I change the dimension to 3D and add an InitialParameter as follow:

typedef RegistrationType::ParametersType ParametersType;

ParametersType initialParameters( transform->GetNumberOfParameters() );

initialParameters[0] = 0.0; // Initial offset in mm along X

initialParameters[1] = 0.0; // Initial offset in mm along Y

initialParameters[2] = 0.0; // Initial offset in mm along Z

Thanks a lot to have a look on my problem with regards,

 

Josiane.
