Hi Luis,
I adapted the example ImageHistogram2.cxx which uses
ScalarImagetoHistogramGenerator to generate a histogram from a 3D image. I
wanted to next threshold the image
using a threshold which I hoped to derive by using the Quantile function.
But I am getting a compile error:
HistogramThreshold.cxx:125: passing
`const main(int, char**)::HistogramType' as `this' argument of `double
itk::Statistics::Histogram<TMeasurement, VMeasurementVectorSize,
TFrequencyContainer>::Quantile(unsigned int, const double&) [with
TMeasurement = double, unsigned int VMeasurementVectorSize = 1,
TFrequencyContainer = itk::Statistics::DenseFrequencyContainer<float>]'
discards qualifiers
I thought it might be a "const" problem so I removed all the const
declarations but I still got a similar error.
Can you help me figure out what the problem is?
Thanks
Radhika
