[Insight-users] priors in itkBayesianClassifierImageFilter

[Bruno Arbter]

Okay, priors can be set via SetInput - but the flag m_UserProvidedPriors in
itkBayesianClassifierImageFilter remains false, and therefore the priors are
not used without changing the constructor.

Is there an example that really uses priors?

Thanks
Bruno
