[ITK-users] Binary Fill hole Image Filter for 3D Image

[Abdelkhalek Bakkari]

Hi Dzenan,


My goal is to obtain the big contour of the 3D image. For this reason, I tried to use Binary Fill hole Image Filter  and after the BinaryContourImageFilter.

Could you provide me another way using ITK, please?


Best regards,

Hi Abdelkhalek,

your image does not have any holes! The input and output images are binary identical (examined using file compare tool). If I modify your input image to also contain a real hole (not connected to image edge or the background), it gets filled properly. See attached.

Dženan

Dear ITK-users,

I tried to adopt the BinaryFillholeImageFilter for 3D image (contour.mha). Unfortunately,  the result which I obtained is not what I expect.

The fragment of  code which I used is :

                                                // Lecture of the contour.mha
                                                typedef itk::Image< unsigned char, 3 > UCharImageType;
                                               typedef itk::ImageFileReader<UCharImageType> ImageReaderType;
                                       ImageReaderType::Pointer reader = ImageReaderType::New();
                                        reader->SetFileName("contour.mha");
                                        reader->Update();

                                               // Binary Fill Hole Image Filter
                                                typedef itk::BinaryFillholeImageFilter< UCharImageType > FilterType;
FilterType::Pointer filter = FilterType::New();
filter->SetInput( reader->GetOutput() );
filter->SetForegroundValue( itk::NumericTraits< unsigned char >::min() );
filter->Update();
                                                // Save the BinaryFillHoleImage
{
typedef itk::ImageFileWriter<UCharImageType> ImageWriterType;
ImageWriterType::Pointer writer = ImageWriterType::New();
writer->SetFileName("BinaryFillHoleImage.mha");
writer->SetInput(filter->GetOutput());
try{
writer->Update();
}catch(itk::ExceptionObject &e){
std::cerr << e << std::endl;
}
}



Thank you in advance.

Kind regards,
