[Insight-users] itk Subtraction Image filter runtime error

[Sachin Jambawalikar]

Hi ,
I'm trying to subtract  two volumes  using itk  SubtractImageFilter.
I get a runtime error   when I do update for subtraction filter.
Error " this application has requested the runtime to terminate in an
unusal way.
please contact  the app support team for more info" 

Can anybody help me on this ???

Regards

typedef itk::Image< float, 3 > ImageType;
typedef itk::SubtractImageFilter<ImageType,ImageType,ImageType>
SubImgFiltertype;


S1Image=LoadImage((const char*)file_name1 );
S2Image=LoadImage((const char*)file_name2);

	SubImgFiltertype::Pointer subfilt=SubImgFiltertype::New();
	subfilt->SetInput1(S1Image);
  subfilt->SetInput1(S2Image);
ImageType::Pointer image=subfilt->GetOutput();
  subfilt->Update();


ImageType::Pointer LoadImage( const char * filename )
{
	VolumeReaderType::Pointer reader;
	ImageType::Pointer image;

	reader = VolumeReaderType::New();
	reader->SetFileName(filename);

	try
	{
		reader->Update();      
		m_LastLoadedImagePath = filename;     
	}
	catch( itk::ExceptionObject &e )
	{
		std::cout<<e<<std::endl;
	}
	catch(...)
	{
		std::cout<<" Unknow exception caught in LoadImage!!!"<<std::endl;
	}

	image = reader->GetOutput();

	return image;
}
