[Insight-users] 3D watershed segmentation problem

[G G]

Hi I have this code:

    const unsigned int InputDimension = 3;
    typedef float InternalPixelType;
    typedef itk::Image< InternalPixelType, InputDimension >
InternalImageType;
    typedef itk::ImageFileReader< InternalImageType > ReaderType;
    ReaderType::Pointer reader = ReaderType::New();
    try
    {
        reader->SetFileName(this->filepath.c_str());
    }
    catch(...)
    {
        return;
    }
    reader->Update();

    const unsigned int OutputDimension = 3;
    typedef itk::RGBPixel<unsigned char> RGBPixelType;
    typedef itk::Image< RGBPixelType, OutputDimension > RGBImageType;
    typedef  itk::ImageFileWriter< RGBImageType > WriterType;
    WriterType::Pointer writer = WriterType::New();
    writer->SetFileName( "outputimage.mhd" );

        typedef   itk::GradientMagnitudeRecursiveGaussianImageFilter<
                                                        InternalImageType,
                                                        InternalImageType
                                                            >
GradientMagnitudeFilterType;

        GradientMagnitudeFilterType::Pointer gradienMagnitudeFilter =
GradientMagnitudeFilterType::New();
        gradienMagnitudeFilter->SetInput( reader->GetOutput() );
        gradienMagnitudeFilter->SetSigma( 1.0 );

        typedef  itk::WatershedImageFilter< InternalImageType >
WatershedFilterType;
        WatershedFilterType::Pointer watershedFilter =
WatershedFilterType::New(); // *from this code i gave error*
        watershedFilter->SetInput( gradienMagnitudeFilter->GetOutput() );
        watershedFilter->SetThreshold(
this->params->Get_watershed_threshold() );
        watershedFilter->SetLevel( this->params->Get_watershed_flood_value()
);

        typedef itk::Functor::ScalarToRGBPixelFunctor< unsigned long >
ColorMapFunctorType;
        typedef WatershedFilterType::OutputImageType  LabeledImageType;
        typedef itk::UnaryFunctorImageFilter<
                                        LabeledImageType,
                                        RGBImageType,
                                        ColorMapFunctorType
                                                        >
ColorMapFilterType;

        ColorMapFilterType::Pointer colorMapFilter =
ColorMapFilterType::New();
        colorMapFilter->SetInput(  watershedFilter->GetOutput() );

        writer->SetInput( colorMapFilter->GetOutput() );

        try
        {
            writer->Update();
        }
        catch( itk::ExceptionObject & excep )
        {
            cerr << "Exception !" << endl;
            cerr << excep.GetDescription() << endl;
            return;
        }


I thing, that it is not wrong, but I get this errors from VS2008

I dont know, where is the problem :( In my other project it works fine...
I will be very happyif you help me
Thank you everybody
