[Insight-users] DeformableRegistration4.cxx error?

Hi Brecht,
The "DeformableRegistration13.cxx" example uses the RegularStepGradientDescent
optimizer for 2D images. Using the same settings should work for your code.
Good luck,
Dawood

Hi all,
I forgot to mention that I found a similar post on the ITK user list back in 2009: http://itk-insight-users.2283740.n2.nabble.com/Problem-with-DeformableRegistration4-cxx-example-td3218635.html
Has anything been resolved since then? I'll try rerunning the example with a RegularStepGradientDescent optimizer.
Has anyone found any acceptable settings for the optimizer? Something along the lines of:
optimizer->MinimizeOn();
optimizer->SetMaximumStepLength(2.00);
optimizer->SetMinimumStepLength(0.001);
optimizer->SetNumberOfIterations(200);
Where and how would you start tuning this optimizer for this fairly large amount of parameters (already in 2D)?
Regards,
Brecht

Subject: DeformableRegistration4.cxx error?
Dear all,
I just tried running Examples/Registration/DeformableRegistration4.cxx/.
Is it normal that the stop condition of the LBFGS optimizer gives me an error: "vnl_lbfgs: Error. Netlib routine lbfgs failed."?
Also, I compared the differences after registration and they are still fairly large (see attachments)
Please find the output of the program below:
