Detailed Description

Parameters

imagin	Pointer to the BImage containing the input image
imagout	Pointer to the BImage which will receive the output image (It must have been allocated beforehand: same dimension as 'imagin')
option	Description of the structuring element: 1 for BLOCK and 0 for CROSS (see remarks for more information)
radius	Vector giving the extensions of the structuring element along each direction of the Space.
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_closing()

void gstlrn::morpho_closing	(	Id	option,
		const 1 &	radius,
		const BImage &	imagin,
		BImage &	imagout,
		bool	verbose
	)

Perform the "closing" of the input image (i.e. a dilation followed by an erosion)

morpho_dilation()

void gstlrn::morpho_dilation	(	Id	option,
		const 1 &	radius,
		const BImage &	imagin,
		BImage &	imagout,
		bool	verbose
	)

Perform the "dilation" of the input image

morpho_erosion()

void gstlrn::morpho_erosion	(	Id	option,
		const 1 &	radius,
		const BImage &	imagin,
		BImage &	imagout,
		bool	verbose
	)

Perform the "erosion" of the input image

morpho_opening()

void gstlrn::morpho_opening	(	Id	option,
		const 1 &	radius,
		const BImage &	imagin,
		BImage &	imagout,
		bool	verbose
	)

Perform the "opening" of the input image (i.e. an erosion followed by a dilation)
