[Insight-users] How can I use LinearInterpolateImageFunction After BilateralImageFilter

[noc]

Hi everyone，

I'm new here to use ITK，and I met some problems now，and really wanna know the solutions，could U help me，please？

 

first，I don't know whether it's Bilinear Interpolation or Linear Interpolation when I use LinearInterpolateImageFunction to process a 2D image.

 

second, how can I use LinearInterpolateImageFunction after BilateralImageFilter? The purpose to do so is that I wanna keep the edge of a CT image, and make the edge more consecutive.

 

In the end，here's the codes I coded (just Bilinear Interpolation, I don't know how to use LinearInterpolateImageFunction)

 

int main()
{
 typedef itk::Image<unsigned short, 2> ImageType;
 typedef itk::ImageFileReader<ImageType> ReaderType;
 typedef itk::GDCMImageIO DICOMType;
 typedef itk::ImageToVTKImageFilter<ImageType> ConnectorType;
 typedef itk::BilateralImageFilter<ImageType, ImageType> FilterType;
 typedef itk::LinearInterpolateImageFunction<ImageType, double> InterpolatorType;

 

 ReaderType :: Pointer reader = ReaderType :: New();
 DICOMType :: Pointer gcdmImageIO = DICOMType :: New();
 ConnectorType :: Pointer connector = ConnectorType :: New();
 FilterType :: Pointer filter = FilterType :: New();
 InterpolatorType :: Pointer interpolator = InterpolatorType::New();

 

 reader->SetImageIO(gcdmImageIO);
 reader->SetFileName("d:/Data/feet/feet.140");

 

 filter->SetInput(reader->GetOutput());
 filter->SetDomainSigma(1.0);
 filter->SetRangeSigma(1.0);

 

 return 0;

}

 

Could U help me, please?

Thanks!

And best wishes!!!
