◆ AfterThreadedGenerateData()

template<class TInputImage , class TProbabilityPrecision = double, class TCentroidValuePrecision = double>

void itk::FCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >::AfterThreadedGenerateData ( )

overrideprotected

FCMClassifierInitializationImageFilter is implemented as a multithreaded filter and needs to perform processing after all processing threads have completed.

Therefore, this implementation provides an AfterThreadedGenerateData() method. This method is executed once per iteration of the FCM algorithm and will update the centroids and calculate the error.

◆ BeforeThreadedGenerateData()

template<class TInputImage , class TProbabilityPrecision = double, class TCentroidValuePrecision = double>

void itk::FCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >::BeforeThreadedGenerateData ( )

overrideprotected

FCMClassifierInitializationImageFilter is implemented as a multithreaded filter and needs to perform processing after the output image has been allocated but before threads are spawned.

Therefore, this implementation provides a BeforeThreadedGenerateData() method. This method is executed once per iteration of the FCM algorithm and will store the old values of the centroids and initialize some variables used internally.

◆ itkNewMacro()

template<class TInputImage , class TProbabilityPrecision = double, class TCentroidValuePrecision = double>

itk::FCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >::itkNewMacro ( Self )

Write the name-value pairs of the class data members to the supplied output stream.

◆ SetNumberOfClasses()

void itk::FCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >::SetNumberOfClasses ( const unsigned int & numOfClasses )

overridevirtual

Set number of classes.

This method calls Superclass::SetNumberOfClasses(numOfClasses) and creates some variables used for centroids calculations. This method also sets the size of the vector of old centroids.

Reimplemented from itk::FuzzyClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >.

◆ ThreadedGenerateData()

template<class TInputImage , class TProbabilityPrecision = double, class TCentroidValuePrecision = double>

void itk::FCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >::ThreadedGenerateData	(	const OutputImageRegionType &	outputRegionForThread,
		ThreadIdType	threadId
	)

overrideprotected

FCMClassifierInitializationImageFilter is implemented as a multithreaded filter.

Therefore, this implementation provides a ThreadedGenerateData() method which is called for each processing thread. The output image data is allocated automatically by the supercalss prior to calling ThreadedGenerateData(). ThreadedGenerateData() can only write to the portion of the output membership image specified by the parameter "outputRegionForThread". This method is executed once per iteration of the FCM algorithm and will set that portion of the membership image and perform some calulations used later to update the centroids.
