[Insight-users] DiscreteGaussianImageFilter in function

[G G]

Hi, I dont solve it, so I try to ask here...
I have this function

template<typename TImageTypePointer, typename TImageType> void
WatershedCompute::
    discreteGaussianFilter(TImageTypePointer inputImage, void *poutputImage)
{
    typedef itk::DiscreteGaussianImageFilter< TImageType, TImageType >
DiscreteGaussianFilterType;
    DiscreteGaussianFilterType::Pointer discreteGaussianFilter =
DiscreteGaussianFilterType::New();
    discreteGaussianFilter->SetInput( inputImage );
    const double gaussianVariance =
this->params->Get_discrete_gaussian_variance();
    const unsigned int maxKernelWidth =
this->params->Get_discrete_gaussian_kernel_width();
    discreteGaussianFilter->SetVariance( gaussianVariance );
    discreteGaussianFilter->SetMaximumKernelWidth( maxKernelWidth );
    discreteGaussianFilter->Update(); // this line
    TImageTypePointer *Pout = (TImageTypePointer *)poutputImage;
    *Pout = discreteGaussianFilter->GetOutput();
    return;
}

And in // this line I have "error"... I dont know, if it is error, because I
get code from another function, which I dont call, I dont know what is the
problem :(


I have another function for example

template<typename TImageTypePointer, typename TImageType> void
WatershedCompute::
    rescaleIntensityFilter(TImageTypePointer inputImage, void *poutputImage,
int min, int max)
{
    typedef itk::RescaleIntensityImageFilter< TImageType, TImageType >
RescaleFilterType;
    RescaleFilterType::Pointer rescaler = RescaleFilterType::New();
    rescaler->SetOutputMinimum( min );
    rescaler->SetOutputMaximum( max );
    rescaler->SetInput( inputImage );
    rescaler->Update();
    TImageTypePointer *Pout = (TImageTypePointer *)poutputImage;
    *Pout = rescaler->GetOutput();
    return;
}

When I call only rescaleIntensityFilter and dont call
discreteGaussianFilterit is OK. Could someone help me, please?
Thanks a lot :-)
