Member Typedef Documentation

Definition at line 44 of file itkOptimizer.h.

Parameters type. It defines a position in the optimization search space.

Definition at line 50 of file itkOptimizer.h.

Definition at line 43 of file itkOptimizer.h.

typedef Array< double > itk::Optimizer::ScalesType

Scale type. This array defines scale to be applied to parameters before being evaluated in the cost function. This allows to map to a more convenient space. In particular this is used to normalize parameter spaces in which some parameters have a different dynamic range.

Member Function Documentation

virtual::itk::LightObject::Pointer itk::Optimizer::CreateAnother ( void  ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

Reimplemented in itk::PowellOptimizer, itk::ParticleSwarmOptimizer, itk::QuaternionRigidTransformGradientDescentOptimizer, itk::VersorTransformOptimizer, itk::VersorRigid3DTransformOptimizer, itk::SPSAOptimizer, itk::SingleValuedNonLinearOptimizer, itk::RegularStepGradientDescentBaseOptimizer, and itk::RegularStepGradientDescentOptimizer.

virtual const ParametersType& itk::Optimizer::GetCurrentPosition ( )
virtual

Get current position of the optimization.

virtual const ParametersType& itk::Optimizer::GetInitialPosition ( )
virtual

Get the position to initialize the optimization.

virtual const char* itk::Optimizer::GetNameOfClass ( ) const
virtual
virtual const ScalesType& itk::Optimizer::GetScales ( )
virtual

Get current parameters scaling.

virtual const std::string itk::Optimizer::GetStopConditionDescription ( ) const
virtual
static Pointer itk::Optimizer::New ( )
static

Method for creation through the object factory.

void itk::Optimizer::operator= ( const Self )
private
void itk::Optimizer::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
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::Object.

Reimplemented in itk::SPSAOptimizer, itk::ParticleSwarmOptimizerBase, itk::PowellOptimizer, itk::SingleValuedNonLinearVnlOptimizer, itk::RegularStepGradientDescentBaseOptimizer, itk::ParticleSwarmOptimizer, and itk::SingleValuedNonLinearOptimizer.

virtual void itk::Optimizer::SetCurrentPosition ( const ParametersType param)
protectedvirtual

Set the current position.

virtual void itk::Optimizer::SetInitialPosition ( const ParametersType param)
virtual

Set the position to initialize the optimization.

void itk::Optimizer::SetScales ( const ScalesType scales)

Set current parameters scaling.
