Constructor & Destructor Documentation

EHitAndMissKernel() [1/3]

eVision.EHitAndMissKernel.EHitAndMissKernel	(	int	startX,
		int	startY,
		int	endX,
		int	endY )

Constructs a EHitAndMissKernel object.

Parameters

startX	The abscissa of the top leftmost element of the kernel. This value must be less than or equal to zero.
startY	The ordinate of the top leftmost element of the kernel. This value must be less than or equal to zero.
endX	The abscissa of the bottom rightmost element of the kernel. This value must be greater than or equal to zero.
endY	The ordinate of the bottom rightmost element of the kernel. This value must be greater than or equal to zero.

The constructor without argument creates a centered kernel of size 3x3.

All the elements of the kernel are initialized with EHitAndMissValue.EHitAndMissValue_DontCare values.

If the object is constructed by specifying the halves of the kernel dimensions, the width (resp. the height) of the kernel is given by 2 * halfSizeX + 1 (resp. 2 * halfSizeY + 1). Otherwise, the width (resp. the height) of the kernel is given by endX - startX + 1 (resp. endY - startY + 1).

EHitAndMissKernel() [2/3]

eVision.EHitAndMissKernel.EHitAndMissKernel	(	uint	halfSizeX,
		uint	halfSizeY )

Parameters

halfSizeX	The half of the kernel width minus 1. This value must be greater than zero.
halfSizeY	The half of the kernel height minus 1. This value must be greater than zero.

EHitAndMissKernel() [3/3]

eVision.EHitAndMissKernel.EHitAndMissKernel

(

)

Constructs a EHitAndMissKernel object.

The constructor without argument creates a centered kernel of size 3x3.

All the elements of the kernel are initialized with EHitAndMissValue.EHitAndMissValue_DontCare values.

If the object is constructed by specifying the halves of the kernel dimensions, the width (resp. the height) of the kernel is given by 2 * halfSizeX + 1 (resp. 2 * halfSizeY + 1). Otherwise, the width (resp. the height) of the kernel is given by endX - startX + 1 (resp. endY - startY + 1).

Member Function Documentation

GetValue()

eVision.EHitAndMissValue eVision.EHitAndMissKernel.GetValue	(	int	x,
		int	y )

Returns the value of an element of the kernel at a given coordinate.

Parameters

x	The abscissa of the element.
y	The ordinate of the element.

SetSize() [1/2]

void eVision.EHitAndMissKernel.SetSize	(	int	startX,
		int	startY,
		int	endX,
		int	endY )

Modify the size of the kernel.

Parameters

startX	The abscissa of the top leftmost element of the kernel. This value must be less than or equal to zero.
startY	The ordinate of the top leftmost element of the kernel. This value must be less than or equal to zero.
endX	The abscissa of the bottom rightmost element of the kernel. This value must be greater than or equal to zero.
endY	The ordinate of the bottom rightmost element of the kernel. This value must be greater than or equal to zero.

halfSizeY	The half of the kernel height minus 1. This value must be greater than zero.

All the elements of the kernel are initialized with EHitAndMissValue.EHitAndMissValue_DontCare values.

If the object is constructed by specifying the halves of the kernel dimensions, the width (resp. the height) of the kernel is given by 2 * halfSizeX + 1 (resp. 2 * halfSizeY + 1). Otherwise, the width (resp. the height) of the kernel is given by endX - startX + 1 (resp. endY - startY + 1).

SetValue()

void eVision.EHitAndMissKernel.SetValue	(	int	x,
