Detailed Description

Abstract base class for optimization solvers.

Provides interface for solving OptimizationProblems in tomographic reconstruction. Concrete implementations include iterative methods (SART, MLEM, CG) and analytical methods (FDK).

Public Member Functions
	Solver (OptimizationProblem &problem)
	Default constructor.
	~Solver () override=0
	Destructor.
CT::Status	solve (Progress *p=nullptr)
	Solves a Problem.
virtual float	defaultInitValue () const =0
	Return default initialization value for the current solver.
const OptimizationProblem &	problem ()
const std::vector< std::unique_ptr< EventHandler > > &	eventHandlers ()
void	configure (const Properties *p) override
	Configure this object instance by de-serializing the given Properties.
void	configuration (Properties *p) const override
	Serialize the current object configuration into the given Properties object.
Public Member Functions inherited from Configurable
virtual void	configureDefaults ()
	Retrieve the properties of this object, replaces values with their defaults and sets it again.
void	registerParameter (ParameterBase *param)
	Register the given Parameter or SubProperty, so that it will be configured during configure()/configuration().
void	unregisterParameter (const ParameterBase *param)
	Remove the given Parameter or SubProperty from the list of registered parameters.
	Configurable (const Configurable &rhs)
	Configurable (Configurable &&rhs) noexcept
Configurable &	operator= (const Configurable &)
Configurable &	operator= (Configurable &&) noexcept

Public Attributes
Parameter< bool >	p_cropFan = {"cropFan", false, *this}
	Whether to apply CropFan in the end of computation.
Parameter< bool >	p_forcePositivity = {"forcePositivity", false, *this}
	Whether to apply a positivity enforcement in the end of computation.
Public Attributes inherited from Configurable
Signal	signalParametersChanged
	Emitted whenever one of the registered Parameters' or SubPropertys' signalValueChanged signal was emitted.

Protected Attributes
OptimizationProblem	m_problem
	View on the problem.
std::vector< std::unique_ptr< EventHandler > >	m_eventHandlers
	Event handlers.
Protected Attributes inherited from Configurable
std::vector< Param >	m_params
	List of all registered Parameter and SubProperty instances.

Member Function Documentation

solve()

CT::Status solve

(

Progress *

p = nullptr

)

Solves a Problem.

This member calls the solveImpl, which is overridden in each solver. Solvers are expected to operate in-place on the currentSolution() member variable of the OptimizationProblem provided at construction.

defaultInitValue()

virtual float defaultInitValue ( ) const

pure virtual

Return default initialization value for the current solver.

Implemented in CG, FDK, MLEM, SART, and SQS.

configure()

void configure ( const Properties * p )

overridevirtual

Configure this object instance by de-serializing the given Properties.

The default implementation will do so automatically for all registered Parameter and SubProperty instances.

See also

configuration() for the inverse functionality

Reimplemented from Configurable.

configuration()

void configuration ( Properties * p ) const

overridevirtual

Serialize the current object configuration into the given Properties object.

The default implementation will do so automatically for all registered Parameter and SubProperty instances.
