[Insight-users] Image Registration Metric Derivative Calculation

[Luis Ibanez]

Hi 田光建,


Simply call the method


     GetDerivative()

or

     GetValueAndDerivative()

on the metric that you are using.

It will return an array with the values of the derivative
of the Metric with respect to the transform parameters.

   Regards,


      Luis
