[Insight-users] itk::VTKImageToImageFilter Questions

[Alexis Cheng]

Hi all,

I'm having a bit of trouble using the itk::VTKImageToImageFilter class. My program crashes on runtime. The following is a snippet of my code.

static const unsigned int Dimension = 2;
typedef  float           PixelType;
typedef itk::Image< PixelType, Dimension >  FixedImageType;
typedef itk::VTKImageToImageFilter<FixedImageType> VTKImageToITKImageType;

vtkSmartPointer<vtkImageData> USImage = vtkSmartPointer<vtkImageData>::New();
VTKImageToITKImageType::Pointer VTKToITKConnector = VTKImageToITKImageType::New();
        
vector<FixedImageType::Pointer> *ImagePanorama;
ImagePanorama = NULL;
vector<FixedImageType::Pointer>::iterator PanoramaIterator;
USImage->SetScalarTypeToUnsignedChar();
USImage->SetDimensions(960,480,1);
USImage->SetSpacing(1,1,1);
USImage = sonixGrabber->GetOutput();
USImage->Update();
                
VTKToITKConnector->SetInput(USImage);
VTKToITKConnector->Execute();
                
FixedImageType::Pointer ITKImagePointer = FixedImageType::New();
ITKImagePointer = VTKToITKConnector->GetImporter()->GetOutput();
ITKImagePointer->Update();

I've isolated the error to the usage of VTKImageToImageFilter. I haven't had any luck finding examples that used this filter. What is the correct pipeline for using this filter? Thank you all in advance.
