Label the connected component of a BImage

Functions
GSTLEARN_EXPORT VectorDouble	morpho_labelling (int option, int flag_size, const BImage &imagin, double ccvoid, bool verbose=false)
GSTLEARN_EXPORT VectorInt	morpho_labelsize (int option, const BImage &imagin)

Detailed Description

Parameters

imagin	Pointer to the BImage containing the one input image
option	Description of the structuring element: 1 for BLOCK and 0 for CROSS (see remarks for more information)
flag_size	1 if output information is labeled in volume of the connected component 0 if output information contains the rank of the connected component
ccvoid	Value assigned to pixels which do not belong to any connected component
verbose	Verbose flag

Remarks

In 2-D, if the central cell is denoted (i,j) and the radius is set to 1, the structuring element contains:

• for CROSS: (i+1,j); (i-1,j); (i,j+1); (i,j-1)
• for BLOCK: (i-1,j-1); (i-1,j); (i-1,j+1); (i,j-1); (i,j+1); (i+1,j-1); (i+1,j); (i+1,j+1)

morpho_labelling()

GSTLEARN_EXPORT VectorDouble morpho_labelling	(	int	option,
		int	flag_size,
		const BImage &	imagin,
		double	ccvoid,
		bool	verbose
	)

Labels the connected components for a BImage

Remarks

The labels are sorted by decreasing sizes and an optional message is issued for displaying the component sizes

morpho_labelsize()

GSTLEARN_EXPORT VectorInt morpho_labelsize	(	int	option,
		const BImage &	imagin
	)

Returns the array of dimensions of the connex components

Remarks

The labels are sorted by decreasing sizes and an optional message is issued for displaying the component sizes
