void Acts::Ccl::labelClusters	(	CellCollection &	cells,
		Connect	connect = Connect()
	)

labelClusters

In-place connected component labelling using the Hoshen-Kopelman algorithm. The Cell type must have the following functions defined: int getCellRow(const Cell&), int getCellColumn(const Cell&) int& getCellLabel(Cell&)

Parameters

[in]	cells	the cell collection to be labeled
[in]	connect	the connection type (see DefaultConnect)

ClusterCollection Acts::Ccl::mergeClusters

(

cells

)

mergeClusters

Merge a set of cells previously labeled (for instance with labelClusters) into actual clusters. The Cluster type must have the following function defined: void clusterAddCell(Cluster&, const Cell&)

Returns

nothing
