Detailed Description

template<class TInputImage, class TProbabilityPrecision = double, class TCentroidValuePrecision = double>
class itk::MSKFCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >

Performs Modified Spatial Kernelized Fuzzy C-Means (MSKFCM) Classification on an image.

This implementation is a modified version of the algorithm MSFKCM proposed by Castro et al. in the paper "Comparison of various fuzzy clustering algorithms in the detection of ROI in lung CT and a modified kernelized-spatial fuzzy c-means algorithm" (Proc. of 10th IEEE Int. Conf. On Inf. Tech. and Appl. in Biom., Corfu, Greece, 2010). This modification consists in the combination of the algorithms SFCM (as in the MSFKCM version) and the KFCM (instead of the KFCM used in the MSFKCM version). The KFCM algorithm was presented in S. C. Chen et al.'s paper "Robust Image Segmentation Using FCM With Spatial Constraints Based on New Kernel-Induced Distance Measure" (IEEE Transactions on Systems, Man, and Cybernetics - Part B: Cybernetics, vol. 34, no. 4, August 2004)

MSKFCMClassifierInitializationImageFilter is implemented as a multithreaded filter. This implementation provides BeforeThreadedGenerateData(), ThreadedGenerateData() and AfterThreadedGenerateData() methods. Documentation of the superclass (FuzzyClassifierInitializationImageFilter) explains multhithreaded support in fuzzy classifiers.

Caveats: The user should set the RBF kernel distance metric.

virtual

Set the pointer to the kernel distance metric to be used.

This kernel distance should be a RBF kernel distance metric.

◆ SetNumberOfClasses()

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

void itk::MSKFCMClassifierInitializationImageFilter< 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 and the length of the vector of the temporary membership matrix.

Reimplemented from itk::FuzzyClassifierInitializationImageFilter< TInputImage, double, double >.

◆ SetStructuringElement()

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

void itk::MSKFCMClassifierInitializationImageFilter< TInputImage, TProbabilityPrecision, TCentroidValuePrecision >::SetStructuringElement ( StructuringElementType & structuringEl )

Set the structuring element to be used in the shaped neighborhood iterator.

◆ ThreadedGenerateData()

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

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

overrideprotected

MSKFCMClassifierInitializationImageFilter 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 MSKFCM algorithm and will set that portion of the membership image and perform some calulations used later to update the centroids.
