void	SetImage (itk::Image< TPixel, VImageDimension > *)

void	SetNumberNodes (int inputNumberNodes)

void	SetVariablesForMerging (int givenSizeOfSmallestRegion, int desiredNumberOfParcels, int givenSizeOfSmallestRegionBeginning)

void	SetBoolsForMerging (bool mergingWithNumberParcels, bool mergingWithSmallestParcel, bool justMergeSmallParcels)

void	GetRandomSeedVoxels ()
	Sets randomly chosen seed voxels (1x1x1 regions) on the segmented image This is done by creating a vector with unique values, which represents the position of a voxel respectively. For this purpose we count all voxels with value one and choose random numbers. More...

void	ParcelGrowthOverFaces ()
	Add appropriate voxels of the segmented part to a region (just 6-connected neighborhood) A voxel is appropriate if the cost function value is high enough. Several constraints have to be fulfilled for this purpose. More...

void	FillOverEdgeOrVertex ()
	Add voxels of the segmented part to an appropriate region (26-connected neighborhood) Checks which voxels still have value one and to which neighborhood-region each one should be added. More...

void	AllocateIsolatedVoxels ()
	Add voxels of the segmented part to an appropriate region (no neighbors necessary) Checks which voxels still have value one and calculates the distance to all parcels. Finally each voxel is added to the region with the smallest distance to it. More...

int	MergeParcels ()
	Merge parcels according to a cost function Looks for the parcel with the smallest number of voxels. Then merges it to a neighborhood-parcel such that the cost function value is small enough. The new number of nodes is returned so we can show them on the GUI. More...

void	SetAppropriateValues ()
	Changes the values of the nodes, such that no gaps exist and it starts with value 1. More...

void	ShowSizeOfRegions ()
	Calculates and shows the size (number of voxels) of all regions on the console. More...

Protected Member Functions
std::vector< double >	GetCenterOfMass (itk::ImageRegionIterator< ImageType > it_region, int valueOfRegion, bool getSizeOfRegions)
	Gives back the center of mass and -if wanted- the size (number of voxels) of a parcel. More...

double	GetDistance (std::vector< double > centerOfMass, typename ImageType::IndexType indexNewVoxel)
	Calculates the distance between two voxels, the position of the first one is given by an index and the position of the second one is given by a vector. More...

double	GetDistanceVector (std::vector< double > centerOfMass, std::vector< double > indexNewVoxel)
	Calculates the distance between two voxels, both positions are given by vectors. More...

int	SmallestValue (std::vector< int > distance)
	Gives back the smallest value of an int-vector. More...

double	SmallestValue (std::vector< double > distance)
	Gives back the smallest value of a double-vector. More...

ImageType::RegionType	ExtendedRegion (typename ImageType::RegionType chosenRegion, typename ImageType::IndexType indexChosenVoxel)
	Extends the region if the chosen voxel lies outside. More...

ImageType::RegionType	ExtendedRegionNotNeighbor (typename ImageType::RegionType chosenRegion, typename ImageType::RegionType smallestRegion)
	Extends the region of a parcel such that the second region lies within. More...

bool	IsUnique (int number, std::vector< int > vec)
	Checks if a number is an element of the vector already. More...

void	GetSizeOfRegions ()
	Calculates the size (number of voxels) of all regions. More...
