Dear list,
I would like to import an 3D ITK image of PixelType
<itk::CovariantVector<float, 3> to a mitk::Image. In my case the ITK
image is the output of itk::GradientImageFilter.
As mitk::ImportImage() does not support the conversion (see the error
below), i tried splitting the ITK image into scalar fields and building
a multi-channel mitk::Image with this scalar fields as channels. While
splitting the vector field works fine using ITK iterators, I can't
figure out how to build a mutli-channel mitk::Image and add the
resulting scalar fields as channels.
May you give me an example of how to accomplish this? There may also be
a smarter way to get it out of the ITK vector field without splitting...
Some Code:
void ItkGradientField::execute( mitk::Image::Pointer inputImage ) {
FloatImage3dType::Pointer itkImage = FloatImage3dType::New();
mitk::CastToItkImage( inputImage, itkImage );
typedef itk::GradientImageFilter<FloatImage3dType, float, float>
GradientType;
GradientType::Pointer gradientFilter = GradientType::New();
gradientFilter->SetInput( itkImage );
gradientFilter->Update();
/* not supported */
//mitk::Image::Pointer result = mitk::ImportItkImage(
gradientFilter->GetOutput() );
QList<FloatImage3dType::Pointer> splittedImages =
splitGradientResultImage( gradientFilter->GetOutput() );
mitk::Image::Pointer result = mitk::ImportItkImage( splittedImages[0] );
/* How to add splittedImages[n] as channels to result ??? */
storeOutputImage(result);
}
Error when calling mitk::ImportImage():
An error occurred. You should save all data and quit the program to
prevent possible data loss.
See the error log for details.
/data/development/mitk/mitk-0.14-src/Core/Code/IO/mitkPixelType.cpp:255:
itk::ERROR: PixelType(0x7fff8acdb670): Pixel type currently not supported.
Thanks in advance,
Simon
