[Insight-users] declaring a ITK registration metric using std::complex<> image

[Rick Shilling]

I want to use a MutualInformationImageToImageMetric type between two images with std::complex<double> at their pixel type:

typedef std::complex< double > COMPLEXPIXEL;
typedef itk::Image< COMPLEXPIXEL , 3>  ImageType;  
typedef itk::MutualInformationImageToImageMetric<ImageType,ImageType> MetricType;
MetricType::Pointer metric  = MetricType::New();

VC++6.0/win2K produces compiler errors listed below regarding instantiating the metric pointer.  Though, I've seen std::complex<double> being used as a pixel type for itk::Image<,> in other examples.  Does anyone know if it is possible to use std::complex<> in the imagetype template for the MutualInformationImageToImageMetric or for any other ITK metric?  

Regards,
Rick
