[ITK-users] Vector image deformable registration

[artioml]

Hello,

I am trying to do BSplines *Deformable registration* of 2D *vector images* -
each pixel is a vector with a length of 3. There is no *example* to perform
such a thing.

I did find a test named:
*itkMeanSquaresImageToImageMetricv4VectorRegistrationTest*
located at: Modules/Registration/Metricsv4/test

I tried to fuse it with *DeformableRegistration4* example

I have replaced the 'PixelType' from '/float/' to '/itk::Vector<double,
3>/'.
And the metric 
*from:*
/typedef itk::CorrelationImageToImageMetricv4<FixedImageType,
MovingImageType >  MetricType;/
*to:*
/typedef itk::VectorImageToImageMetricTraitsv4< ImageType, ImageType,
ImageType, vectorLength, double > MetricTraitsType;
typedef itk::MeanSquaresImageToImageMetricv4< ImageType, ImageType,
ImageType, double, MetricTraitsType > MetricType;/

When I try to compile it I get long error list. The first error *dump is
here bellow*. Do you have any idea what I did wrong?
