Member Typedef Documentation

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

protected

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

Member Function Documentation

virtual const ParametersType& itk::MultipleValuedNonLinearVnlOptimizer::GetCachedCurrentPosition ( )

virtual

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, for mathematical validation you should rather call GetValue().

Run-time type information (and related methods).

Reimplemented from itk::MultipleValuedNonLinearOptimizer.

Reimplemented in itk::LevenbergMarquardtOptimizer.

CostFunctionAdaptorType* itk::MultipleValuedNonLinearVnlOptimizer::GetNonConstCostFunctionAdaptor ( void ) const

protected

The purpose of this method is to get around the lack of const correctness in vnl cost_functions and optimizers

protectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::MultipleValuedNonLinearOptimizer.

virtual void itk::MultipleValuedNonLinearVnlOptimizer::SetCostFunction ( MultipleValuedCostFunction * costFunction )

pure virtual

Set the 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 itkCostFunction. As a consequence each derived optimizer should construct its own CostFunctionAdaptor when overloading this method

Implemented in itk::LevenbergMarquardtOptimizer.

protected

void itk::MultipleValuedNonLinearVnlOptimizer::SetUseCostFunctionGradient ( bool )

Define if the Cost function should provide a customized Gradient computation or the gradient can be computed internally using a default approach
