Member Typedef Documentation

typedef ReceptorMemberCommand< Self > itk::SingleValuedNonLinearVnlOptimizerv4::CommandType

Command observer that will interact with the ITKVNL cost-function adaptor in order to generate iteration events. This will allow to overcome the limitation of VNL optimizers not offering callbacks for every iteration

Return Cached Values. These method have the advantage of not triggering a recomputation of the metric value, but it has the disadvantage of returning a value that may not be the one corresponding to the current parameters. For GUI update purposes, this method is a good option.

Note: The metric value is cached in the base class, retrieved via GetValue().

void itk::SingleValuedNonLinearVnlOptimizerv4::IterationReport ( const EventObject & event )

private

The purpose of this method is to get around the lack of iteration reporting in VNL optimizers. By interfacing directly with the ITK cost function adaptor we are generating here Iteration Events. Note the iteration events here are produce PER EVALUATION of the metric, not per real iteration of the vnl optimizer. Optimizers that evaluate the metric multiple times at each iteration will generate a lot more of Iteration events here.

virtual void itk::SingleValuedNonLinearVnlOptimizerv4::SetMetric ( MetricType * metric )

overridepure virtual

Set the metric (cost function). This method has to be overloaded by derived classes because the CostFunctionAdaptor requires to know the number of parameters at construction time. This number of parameters is obtained at run-time from the itkObjectToObjectMetric. As a consequence each derived optimizer should construct its own CostFunctionAdaptor when overloading this method

Implemented in itk::LBFGSBOptimizerv4, itk::LBFGSOptimizerv4, itk::LBFGSOptimizerBasev4< TInternalVnlOptimizerType >, itk::LBFGSOptimizerBasev4< vnl_lbfgs >, itk::LBFGSOptimizerBasev4< vnl_lbfgsb >, and itk::AmoebaOptimizerv4.

virtual void itk::SingleValuedNonLinearVnlOptimizerv4::StartOptimization ( bool doOnlyInitialization = false )

overridevirtual

Run the optimization.

Parameters

doOnlyInitialization This is false by default. It should only be set to true for special cases when the class should be initialized to perform optimization, but no optimization should be run. For example, itkMultiGradientOptimizerv4 needs to do this.
