Hello,
I would recommend using the itk::LabelImageToShapeLabelMapFilter in the current
master branch of the ITK repository:
https://itk.org/Doxygen/html/classitk_1_1LabelImageToShapeLabelMapFilter.html
The LabelGeometryImageFilter is only in the Review module and has several known
computational and performance issues.

Subject: [ITK-dev] Problem with hash using LabelGeometryImageFilter
Dear all,
I need some help with the following problem:
I have a mask representing the ROI of an image. I wanted now to use the
LabelGeometryImageFilter to calculate the volume and eigenvalues of this mask.
For this I have the following code:
typedef itk::Image< T, R > ImageType;
typename ImageType::Pointer mask;
typedef itk::ImageFileReader< ImageType > ReaderType;
typename ReaderType::Pointer readerMask = ReaderType::New();
readerMask->SetFileName(config.voiName);
//get the output of the VOI mask
mask = readerMask->GetOutput();
try{
readerMask->Update();
}
catch(itk::ExceptionObject &excp){
std::cerr << excp <<std::endl;
}
double origin[3] = {0.0, 0.0, 0.0};
mask->SetOrigin(origin);
typedef itk::LabelGeometryImageFilter< ImageType >
LabelGeometryImageFilterType;
typename LabelGeometryImageFilterType::Pointer labelGeometryImageFilter =
LabelGeometryImageFilterType::New();
If I want to compile this, I already get the error:
Error: no match for call to ‘{const hasher {aka const __gnu_cxx: hash<float>})
(const key_type&)
Does anyone know where the problem is coming from and how I could solve this?
Thanks a lot !
Regards
Elli
