[Insight-users] How to choose an optimizer for Historgramimagetoimagemetric

Wed Oct 12 10:33:01 EDT 2005

insight-users-request at itk.org，您好！ 

  I found that the derived class of  HistogramImageToImageMetric, such as: MutualInformationHistogramImageToImageMetric
and NormalizedMutualInformationHistogramImageToImageMetric, has no method of GetDerivate(). Does this mean that  we
could not apply RegularStepsGradientDescentOptimizer as an optimzer to registration work when using such metric. Is there 
any prinprle for one metric to choose a propriate optimizer.

 Thinks a lot :)
