[Insight-users] Image Registration Metric Derivative Calculation

[田光建]

Thank you for your answer, Luis. If I want to develope my own special image metric, I need to calculate the derivative. What should I do? Should I derive my own class from itk class and override the GetDerivative() and GetValueAndDerivative()?> Date: Wed, 23 Jul 2008 10:29:29 -0400> From: luis.ibanez at kitware.com> To: gjtian at hotmail.com> CC: insight-users at itk.org> Subject: Re: [Insight-users] Image Registration Metric Derivative Calculation> > > 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> > > ------------------> 田光建 wrote:> > Hi,All> > > > I want to know how to calculate the metric derivative in ITK for > > registration.
