[ITK-users] ScalarImageToTextureFeaturesFilter

[Zou Jing]

Dear all,

I am new to ITK and I want to calculate texture features of NIFTI images.
But the result of different images are all the same, the result are 1 0 1 0 0 0
I’d appreciate it if you could help me .
Many thanks.

Here attached the code :

#include "itkImage.h"
#include "itkScalarImageToTextureFeaturesFilter.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"
#include "itkNiftiImageIO.h"


typedef itk::Image<float, 3> ImageType;


int main()
{
typedef itk::ImageFileReader<ImageType>ReaderType;
ReaderType::Pointer reader = ReaderType::New();
ReaderType::Pointer reader1 = ReaderType::New();


reader->SetFileName("C:/Users/studentx/Downloads/lung_data/NormalLung2/F63y/F63_2013.nii");
reader->Update();

reader1->SetFileName("C:/Users/studentx/Downloads/lung_data/NormalLung2/F63y/F63_2013_mask.nii");
reader1->Update();


typedef itk::Statistics::ScalarImageToTextureFeaturesFilter<ImageType> TextureFilterType;
TextureFilterType::Pointer textureFilter = TextureFilterType::New();
textureFilter->SetInput(reader->GetOutput());
textureFilter->SetMaskImage(reader1->GetOutput());

textureFilter->Update();

const TextureFilterType::FeatureValueVector* output = textureFilter->GetFeatureMeans();
for (unsigned int i = 0; i < output->size(); ++i)
{
std::cout << (*output)[i] << std::endl;
}

return EXIT_SUCCESS;
}
