Inheritance diagram for itk::Statistics::GaussianMixtureModelComponent< TSample >:
On every iteration of EM estimation, this class's GenerateData method is called to compute the new distribution parameters.
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.

| 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
| bool itk::Statistics::MixtureModelComponentBase< TSample >::AreParametersModified | ( | ) | [inherited] |
returns the value of parameter modified tag
| void itk::Statistics::MixtureModelComponentBase< TSample >::AreParametersModified | ( | bool | flag | ) | [inherited] |
sets the parameters modified tag. if one or more of the membership funtion's parameters are changed, then flag should be true
| static void itk::LightObject::BreakOnError | ( | ) | [static, inherited] |
This method is called when itkExceptionMacro executes. It allows the debugger to break on error.
| double itk::Statistics::GaussianMixtureModelComponent< TSample >::CalculateParametersChange | ( | ) | [protected] |
Returns the sum of squared changes in parameters between iterations
| virtual LightObject::Pointer itk::Object::CreateAnother | ( | ) | const [virtual, inherited] |
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::LightObject.
| void itk::Statistics::MixtureModelComponentBase< TSample >::CreateWeightArray | ( | ) | [protected, inherited] |
allocates the weights array
| virtual void itk::Object::DebugOff | ( | ) | const [virtual, inherited] |
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.
| void itk::Statistics::MixtureModelComponentBase< TSample >::DeleteWeightArray | ( | ) | [protected, inherited] |
deallocates the weights array
| double itk::Statistics::MixtureModelComponentBase< TSample >::Evaluate | ( | MeasurementVectorType & | measurements | ) | [inherited] |
returns the membership score of the "measurements" vector
| void itk::Statistics::GaussianMixtureModelComponent< TSample >::GenerateData | ( | ) | [protected, virtual] |
Computes the new distribution parameters
Reimplemented from itk::Statistics::MixtureModelComponentBase< TSample >.
| Command* itk::Object::GetCommand | ( | unsigned long | tag | ) | [inherited] |
Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.
| bool itk::Object::GetDebug | ( | ) | const [inherited] |
Get the value of the debug flag.
