typedef SmartPointer<const Self> itk::Optimizer::ConstPointer

Reimplemented from itk::Object. Reimplemented in itk::AmoebaOptimizer, itk::ConjugateGradientOptimizer, itk::GradientDescentOptimizer, itk::LBFGSOptimizer, itk::LevenbergMarquardtOptimizer, itk::MultipleValuedNonLinearOptimizer, itk::MultipleValuedNonLinearVnlOptimizer, itk::NonLinearOptimizer, itk::OnePlusOneEvolutionaryOptimizer, itk::QuaternionRigidTransformGradientDescentOptimizer, itk::RegularStepGradientDescentBaseOptimizer, itk::RegularStepGradientDescentOptimizer, itk::SingleValuedNonLinearOptimizer, itk::SingleValuedNonLinearVnlOptimizer, and itk::VersorTransformOptimizer. Definition at line 44 of file itkOptimizer.h.

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

Parameters type. It defines a position in the optimization search space. Reimplemented in itk::MultipleValuedNonLinearOptimizer, itk::MultipleValuedNonLinearVnlOptimizer, itk::NonLinearOptimizer, itk::QuaternionRigidTransformGradientDescentOptimizer, and itk::SingleValuedNonLinearOptimizer. Definition at line 54 of file itkOptimizer.h.

typedef SmartPointer<Self> itk::Optimizer::Pointer

Reimplemented from itk::Object. Reimplemented in itk::AmoebaOptimizer, itk::ConjugateGradientOptimizer, itk::GradientDescentOptimizer, itk::LBFGSOptimizer, itk::LevenbergMarquardtOptimizer, itk::MultipleValuedNonLinearOptimizer, itk::MultipleValuedNonLinearVnlOptimizer, itk::NonLinearOptimizer, itk::OnePlusOneEvolutionaryOptimizer, itk::QuaternionRigidTransformGradientDescentOptimizer, itk::RegularStepGradientDescentBaseOptimizer, itk::RegularStepGradientDescentOptimizer, itk::SingleValuedNonLinearOptimizer, itk::SingleValuedNonLinearVnlOptimizer, and itk::VersorTransformOptimizer. 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. Reimplemented in itk::NonLinearOptimizer. Definition at line 62 of file itkOptimizer.h.

typedef Optimizer itk::Optimizer::Self

Standard class typedefs. Reimplemented from itk::Object. Reimplemented in itk::AmoebaOptimizer, itk::ConjugateGradientOptimizer, itk::GradientDescentOptimizer, itk::LBFGSOptimizer, itk::LevenbergMarquardtOptimizer, itk::MultipleValuedNonLinearOptimizer, itk::MultipleValuedNonLinearVnlOptimizer, itk::NonLinearOptimizer, itk::OnePlusOneEvolutionaryOptimizer, itk::QuaternionRigidTransformGradientDescentOptimizer, itk::RegularStepGradientDescentBaseOptimizer, itk::RegularStepGradientDescentOptimizer, itk::SingleValuedNonLinearOptimizer, itk::SingleValuedNonLinearVnlOptimizer, and itk::VersorTransformOptimizer. Definition at line 41 of file itkOptimizer.h.

typedef Object itk::Optimizer::Superclass

Reimplemented from itk::Object. Reimplemented in itk::AmoebaOptimizer, itk::ConjugateGradientOptimizer, itk::GradientDescentOptimizer, itk::LBFGSOptimizer, itk::LevenbergMarquardtOptimizer, itk::MultipleValuedNonLinearOptimizer, itk::MultipleValuedNonLinearVnlOptimizer, itk::NonLinearOptimizer, itk::OnePlusOneEvolutionaryOptimizer, itk::QuaternionRigidTransformGradientDescentOptimizer, itk::RegularStepGradientDescentBaseOptimizer, itk::RegularStepGradientDescentOptimizer, itk::SingleValuedNonLinearOptimizer, itk::SingleValuedNonLinearVnlOptimizer, and itk::VersorTransformOptimizer.

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

Get current position of the optimization.

virtual ParametersType itk::Optimizer::GetInitialPosition (    )  const [virtual]

Get the position to initialize the optimization.

virtual const ScalesType& itk::Optimizer::GetScales (    )  [virtual]

Get current parameters scaling.

Pointer itk::Optimizer::New (    )  [static]

Method for creation through the object factory. Reimplemented from itk::Object.
