[Insight-users] itkScalarImageToHistogramGenerator

[Chr. Rossmanith]

Hi,

I'd like to get some histogram quantiles from a masked image. The mask 
is create by binary thresholding the input image.

If I choose itk::Statistics::MaskedImageToHistogramFilter and use 
Quantile(0, 0.5) it gives me nan. Next idea is to use 
itk::Statistics::ScalarImageToHistogramGenerator and set the histogram 
frequencies for measurements below the given threshold to zero. Now the 
problem is that 
itk::Statistics::ScalarImageToHistogramGenerator->GetOutput() returns a 
const histogram I can't modify e.g. by SetFrequencyOfMeasurement().

Any hints how to solve my problem?
