Label the connected component of a BImage

Functions
	gstlrn::morpho_labelling (Id option, Id flag_size, const BImage &imagin, double ccvoid, bool verbose=false)
	gstlrn::morpho_labelsize (Id 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)

Function Documentation

morpho_labelling()

gstlrn::morpho_labelling	(	Id	option,
		Id	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()

gstlrn::morpho_labelsize	(	Id	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
