Hi Luis,
Thanks for the quick response.
But i dont see that the error was due to my Imagetype 's but the
source code of MRIBiasFieldCorrectionFilter.Let me give the full
description of my observation.
First: My source code for your refernce.
//
// I have a template class which gives me the ITK image when
passed a pixel buffer // of any type.
// this template class internally creates a ImageType with
the pixel type passed
typedef BufferToImageConversion<unsigned char> ConverterType;
typedef ConverterType::ImageType ImageType;
ConverterType converter;
ConverterType::ImagePointer imageMRI =
converter.GetImage(pMRI);
typedef itk::MRIBiasFieldCorrectionFilter<ImageType, ImageType,
ImageType> Corrector;
Corrector::Pointer filter = Corrector::New() ;
filter->SetInput(imageMRI); // SO THE IMAGE IS OF TYPE UNSIGNED
CHAR.
filter->IsBiasFieldMultiplicative(true) ;
filter->SetTissueClassStatistics(classMeans,classSigma) ;
filter->SetUsingInterSliceIntensityCorrection(true);
filter->SetSlicingDirection(2) ;
ProgressUpdate(35, "Apply filter ", MRIVolumeName);
filter->Update();
ImageType::Pointer imageMRIINHCOR = filter->GetOutput();
Now My observations is...
As the compiler points the error as ...
=> m_EnergyFunction->SetImage(m_InternalInput) ;
=> itk\Algorithms\itkMRIBiasFieldCorrectionFilter.txx(233)
the error could ber with the m_EnergyFunction or
m_InternalInput.The creation of these two is in the source is
given as
// typedef MRIBiasEnergyFunction<TInputImage, ImageMaskType,
BiasFieldType>
//
EnergyFunctionType;
// typedef typename EnergyFunctionType::Pointer
EnergyFunctionPointer;
// EnergyFunctionPointer m_EnergyFunction ;
// typedef Image< float, itkGetStaticConstMacro(ImageDimension) >
InternalImageType ;
// InternalImagePointer m_InternalInput
And i dont see any code related to casting the float image to
unsigned char image.
Am i missing any thing here??
Do i need to do plug-in any extrac code here??
Please help me..
Thank you for your time and interest,
