Maybe I am not getting the algorithm right... and the hard-coded values are working correctly.

Where is this -5 coming from?

ITKTextureFeatures/include/itkCoocurrenceTextureFeaturesImageFilter.hxx

Line 176 in 6787fc5

if( inputNIt.GetCenterPixel() < ( - 5) ) //the pixel is outside of the mask

Thinking out-loud, just in case, will figure out!

It is the Digitizer that set all these hardcoded values.

ITKTextureFeatures/include/itkDigitizerFunctor.h

Lines 66 to 82 in 6787fc5

inline TOutput operator()(const MaskPixelType & maskPixel,
const PixelType & inputPixel) const
{
if(maskPixel != m_MaskValue)
{
return - 10;
}
else if (inputPixel < this->m_Min || inputPixel >= m_Max)
{
return - 1;
}
else
{
return Math::Floor< TOutput >((inputPixel - m_Min)/((m_Max-m_Min)/ (float)m_NumberOfBinsPerAxis));
}
}
