Detailed Description

template<class TSample>
class itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >

This class generates the parameter estimates for a mixture model using expectation maximization strategy.

The first template argument is the type of the target sample data. This estimator expects one or more mixture model component objects of the classes derived from the MixtureModelComponentBase. The actual component (or module) parameters are updated by each component. Users can think this class as a strategy or a integration point for the EM procedure. The initial proportion (SetInitialProportions), the input sample (SetSample), the mixture model components (AddComponent), and the maximum iteration (SetMaximumIteration) are required. The EM procedure terminates when the current iteration reaches the maximum iteration or the model parameters converge.

Recent API changes: The static const macro to get the length of a measurement vector, MeasurementVectorSize has been removed to allow the length of a measurement vector to be specified at run time. It is now obtained at run time from the sample set as input. Please use the function GetMeasurementVectorSize() to get the length.

template<class TSample >
int itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::AddComponent ( ComponentType component  ) 

Adds a new component (or class).

template<class TSample >
int itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::AddComponent ( ComponentType component  ) 

Adds a new component (or class).

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) const [inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) [inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

static void itk::LightObject::BreakOnError (  )  [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

Turn debugging output off.

virtual void itk::Object::DebugOn (  )  const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete (  )  [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::GenerateData (  )  [protected]

Starts the estimation process

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::GenerateData (  )  [protected]

Gets the membership function specified by componentIndex argument.

static void itk::Object::SetGlobalWarningDisplay ( bool  flag  )  [static, inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

Referenced by itk::Object::GlobalWarningDisplayOff(), and itk::Object::GlobalWarningDisplayOn().

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::SetInitialProportions ( ProportionVectorType propotion  ) 

Set/Gets the initial proportion values. The size of proportion vector should be same as the number of component (or classes)

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::SetInitialProportions ( ProportionVectorType propotion  ) 

Set/Gets the initial proportion values. The size of proportion vector should be same as the number of component (or classes)

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::SetMaximumIteration ( int  numberOfIterations  ) 

Set/Gets the maximum number of iterations. When the optimization process reaches the maximum number of interations, even if the class parameters aren't converged, the optimization process stops.

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::SetMaximumIteration ( int  numberOfIterations  ) 

Set/Gets the maximum number of iterations. When the optimization process reaches the maximum number of interations, even if the class parameters aren't converged, the optimization process stops.

void itk::Object::SetMetaDataDictionary ( const MetaDataDictionary rhs  )  [inherited]
Returns:
Set the MetaDataDictionary
virtual void itk::Object::SetReferenceCount ( int   )  [virtual, inherited]

Sets the reference count (use with care)

Reimplemented from itk::LightObject.

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::SetSample ( const TSample *  sample  ) 

Sets the target data that will be classified by this

void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::SetSample ( const TSample *  sample  ) 

Sets the target data that will be classified by this

virtual void itk::Object::UnRegister (  )  const [virtual, inherited]

Decrease the reference count (release by another object).

Reimplemented from itk::LightObject.

template<class TSample >
void itk::Statistics::ExpectationMaximizationMixtureModelEstimator< TSample >::Update (  ) 

Runs the optimization process.
