[Insight-users] Problem with itkConvolutionImageFilter from git

[Jothy]

Hi Cory,

I use QtCreator, so the cmake lists is auomagically managed by qmake. In
fact  I don't even know how to create cmakeLists.txt and I never required
with QtCreator.

I have managed to make a simple function as shown below.

It converts 2 vtkImageData into itkImages, both are 3D. The conversion works
pretty well and verified with old itkConvolutionImageFilter. Then I convolve
with the latest filter. I copied all the necessary files from itk4.0 to the
src folder such as itkDivideByConstantImageFilter,....

Hope you will be able to manage with this

#include"itkVTKImageToImageFilter.h"

#include "itkImageToVTKImageFilter.h"

#include"itkImage.h"

#include"itkConvolutionImageFilter.h"

#include"vtkImageData.h"

#include"QDebug"

void main(vtkImageData* input,vtkImageData* kernel)

{

//Convert input vtkImageData to itkImage

typedef  itk::Image<unsigned int,3> ImageType;

typedef  itk::VTKImageToImageFilter<ImageType>VTKImageToImageType;

VTKImageToImageType::Pointer converter=VTKImageToImageType::New();

converter->SetInput(input->GetOutput());

converter->Update();

//Convert kernel vtkImageData to itkImage

typedef  itk::Image<unsigned int,3> ImageTypeKernel;

typedef itk::VTKImageToImageFilter<ImageTypeKernel>VTKImageToImageTypeKernel;

VTKImageToImageTypeKernel::Pointer
converterKernel=VTKImageToImageTypeKernel::New();

converterKernel->SetInput(kernel);

converterKernel->Update();

//Crashes while executing htis

qDebug()<<"Convolving....";

typedef  itk::ConvolutionImageFilter<ImageType> ConvolutionFilterType;

ConvolutionFilterType::Pointer convoluter= ConvolutionFilterType::New();

convoluter->SetInput(converter->GetOutput());

convoluter->SetImageKernelInput(converterKernel->GetOutput());

//convoluter->SetOutputRegionModeToSame();

convoluter->Update();

qDebug()<<"Convolving done....";

}

Thanks

Jothy
