Member Function Documentation

template<class LABEL, class VOXEL>

void i3d::LabeledImage3d< LABEL, VOXEL >::CreateRegions	(	Image3d< VOXEL > &	,
		const Neighbourhood &	nb = `nb3D_6`
	)

CreateRegions performs region labeling algorithm on an input Image3d<VOXEL> image. Size of *this LabeledImage3d will be same as of the input image. Information about regions is stored into this->components container. Neigbourhood nb is expected to be symetric. If it is not, the algorithm create symetric neigbourhood from offsets (x, y, z) of nb where (x <= 0 && y == 0 && z == 0) || (y < 0 && z == 0) || (y <= 0 && z < 0)

template<class LABEL, class VOXEL>

void i3d::LabeledImage3d< LABEL, VOXEL >::CreateRegionsFF	(	Image3d< VOXEL > &	,
		const Neighbourhood &	nb = `nb3D_6`
	)

The results are same as for CreateRegions function. Different algorithm (based on FloodFill) is used. Neighbourhood nb3D_6 is imlicitly assumed

template<class LABEL, class VOXEL>

void i3d::LabeledImage3d< LABEL, VOXEL >::CreateForegroundRegionsFF	(	const Image3d< VOXEL > &	,
		const Neighbourhood &	nb = `nb3D_6`
	)

If we know the background needn't be labeled we can speed up the labeling process.

template<class LABEL, class VOXEL>

template<class Predicate>

void i3d::LabeledImage3d< LABEL, VOXEL >::MergeComponents	(	LABEL	comp,
		Predicate	pred
	)			`[inline]`

Component comp is merged with all components for which pred holds.

template<class LABEL, class VOXEL>

void i3d::LabeledImage3d< LABEL, VOXEL >::MergeComponents	(	LABEL	comp1,
		LABEL	comp2
	)

components comp1 and comp2 are merged

template<class LABEL, class VOXEL>

template<class T>

bool i3d::LabeledImage3d< LABEL, VOXEL >::Convert ( Image3d< T > & img ) [inline]

function converts LabeledImage3d to Image3d if it is possible (i.e number of components < max value of Image3d type) List of components is lost. Returned value indicate whether conversion was successful.

template<class LABEL, class VOXEL>

size_t i3d::LabeledImage3d< LABEL, VOXEL >::NumberOfComponents ( ) [inline]

return number of components
