[Insight-users] About voxel counting for Binary image

[Xiaopeng Yang]

Hello Users,

 

I applied ITKStatisticsImageFilter to count the number of voxels for a
series of Binary image. But I always get zero. Here is my code:

 

typedef itk::StatisticsImageFilter<OutputImageType>
StatisticsImageFilterType;

StatisticsImageFilterType::Pointer nrOfVoxelsInMask =
StatisticsImageFilterType::New();

  

nrOfVoxelsInMask->SetInput(filterBM->GetOutput());

 

std::cout<<"Number of Voxel"<<": " << nrOfVoxelsInMask->GetSum()<<std::endl;

 

 

"fiterBM" is the output (Binary images) of segmentation algorithm. 

 

Could you please give me any ideas?

 

Thanks,

Yang
