[Insight-users] Level Set Segmentation ITK

[Gupt]

Hello,

I'm using Level Set Segmentation for my project and am trying to develop my
own speed function. I've included the file
itkSegmentationLevelSetImageFilter.h and then was adding some functions to
this file and I realized that with the original header file I'm getting
errors. Below is a very simple program where I'm creating an instance of a
pointer to this filter and I'm getting the error that follows the program.
I've tried changing data types but I'm unable to get rid of this error.
Please help... Thank you.

#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"
#include "itkSegmentationLevelSetImageFilter.h"

int main( int argc, char *argv[] )
{
  typedef   float           InternalPixelType;
  const unsigned int    Dimension = 2;
  typedef itk::Image< InternalPixelType, Dimension >  InternalImageType;
	
	typedef itk::SegmentationLevelSetFunction<InternalImageType,
InternalImageType> SLSfilter;
	
// ACTUAL LEVEL SET starts

	SLSfilter::Pointer multipleLevelSet = SLSfilter::New();
	
  return 0;
}

Originally I had a longer program with the speed function and I was landing
into the error below. Then I reduced the program to the very basic (above)
and still I get the error.

Thank you for your help...
