Hello,
I am performing a two-stage registration, being the last stage a deformable one.
The deformable stage uses the itkLBFGSBOptimizerv4.h
optimizer.
The deformable stage is converging too fast and certainly with not a good solution.
Those are the tuning parameters:
doptimizer->SetScalesEstimator(scalesEstimator);
doptimizer->SetSolutionAccuracy(1e-4);
doptimizer->SetHessianApproximationAccuracy(5);
doptimizer->SetMaximumIterations(100);
doptimizer->SetMaximumLineSearchEvaluations(10);
Any suggestion on which parameter I should try modifications?
Also, is it a good idea to use the scales estimator for that optimizer?
Thanks.
