Constructor & Destructor Documentation

__init__() [1/3]

None eVision.EHitAndMissKernel.__init__	(		self,
		int	startX,
		int	startY,
		int	endX,
		int	endY )

Constructs a eVision.EHitAndMissKernel object.

Remarks:

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

All the elements of the kernel are initialized with eVision.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).

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.

__init__() [2/3]

None eVision.EHitAndMissKernel.__init__	(		self,
		int	halfSizeX,
		int	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.

__init__() [3/3]

(

self

)

Returns the abscissa of the bottommost element of the kernel.

GetValue()

eVision.EHitAndMissValue eVision.EHitAndMissKernel.GetValue	(		self,
		int	x,

Parameters

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

SetSize() [1/2]

None eVision.EHitAndMissKernel.SetSize	(		self,
		int	halfSizeX,
		int	halfSizeY )

Modify the size of the kernel.

Remarks:

All the elements of the kernel are initialized with eVision.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).

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.
