Performs some miscellaneous operations on BImages

Functions
void	gstlrn::morpho_distance (Id option, const 1 &radius, bool flagDistErode, BImage &imagin, 1 &dist, bool verbose=false)
	gstlrn::gridcell_neigh (Id ndim, Id option, Id radius, bool flag_center=true, bool verbose=false)

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)
radius	Vector giving the extensions of the structuring element along each direction of the Space.
flagDistErode	Inflate the grain; 0 Reduce the grain
dist	Contains the vector of returned distances
iptr0	UID where the angle calculation will be calculated
flag_center	True to omit the center
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)

gridcell_neigh()

gstlrn::gridcell_neigh	(	Id	ndim,
		Id	option,
		Id	radius,
		bool	flag_center,
		bool	verbose
	)

Create the array of index shifts (relatively to the center cell) for a dilation by 'radius' of a regular grid

morpho_distance()

void gstlrn::morpho_distance	(	Id	option,
		const 1 &	radius,
		bool	flagDistErode,
		BImage &	imagin,
		1 &	dist,
		bool	verbose
	)

Returns the vector of distances from the grain to the edge
