Constructor & Destructor Documentation

__init__() [1/3]

None eVision.EMovingAverage.__init__

(

self

)

Constructs an eVision.EMovingAverage object.

Remarks:

The default constructor constructs a void moving average context. A void moving average context has no internal buffers allocated and cannot be used for integration. Use the eVision.EMovingAverage.SetSize member after construction, or the initializing constructor instead. The sizing constructor constructs and initializes a moving average context.

__init__() [2/3]

None eVision.EMovingAverage.__init__	(		self,
		int	period,
		int	width,
		int	height,
		bool	internalAllocationScheme )

Constructs an eVision.EMovingAverage object.

Remarks:

The default constructor constructs a void moving average context. A void moving average context has no internal buffers allocated and cannot be used for integration. Use the eVision.EMovingAverage.SetSize member after construction, or the initializing constructor instead. The sizing constructor constructs and initializes a moving average context.

Parameters

period	Number of images on which to integrate. A power of 2 is recommended.
width	Image width (all images used for averaging must be of the same size).
height	Image height (all images used for averaging must be of the same size).
internalAllocationScheme	Buffer allocation scheme. When true, the moving average context provides the image to be acquired into (see member eVision.EMovingAverage.SrcImage).

__init__() [3/3]

None eVision.EMovingAverage.__init__	(		self,
		int	period,
		int	width,
		int	height )

Constructs an eVision.EMovingAverage object.

Remarks:

The default constructor constructs a void moving average context. A void moving average context has no internal buffers allocated and cannot be used for integration. Use the eVision.EMovingAverage.SetSize member after construction, or the initializing constructor instead. The sizing constructor constructs and initializes a moving average context.

Parameters

period	Number of images on which to integrate. A power of 2 is recommended.
width	Image width (all images used for averaging must be of the same size).
height	Image height (all images used for averaging must be of the same size).

Member Function Documentation

Average() [1/2]

None eVision.EMovingAverage.Average	(		self,
		eVision.EROIBW8 | None	destinationImage )

Performs averaging of the source image with the preceding ones, and computes the de-noised image.

Remarks:

The overload with only the destinationImage may be used only when the buffer allocation scheme has been set to internal (see eVision.EMovingAverage.SetSize or eVision.EMovingAverage.__init__)

Parameters

destinationImage

Pointer to the destination image.

Average() [2/2]

None eVision.EMovingAverage.Average	(		self,
		eVision.EROIBW8 | None	sourceImage,
		eVision.EROIBW8 | None	destinationImage )

Performs averaging of the source image with the preceding ones, and computes the de-noised image.

Remarks:

The overload with only the destinationImage may be used only when the buffer allocation scheme has been set to internal (see eVision.EMovingAverage.SetSize or eVision.EMovingAverage.__init__)

Parameters

sourceImage	Pointer to the source image.
destinationImage	Pointer to the destination image.

ImageHeight()

int eVision.EMovingAverage.ImageHeight

(

self

)

Gets the image height.

ImageWidth()

int eVision.EMovingAverage.ImageWidth

(

self

)

Gets the image width;.

InternalAllocationScheme()

bool eVision.EMovingAverage.InternalAllocationScheme

(

self

)

Gets the buffer allocation scheme.

When true, the moving average context provides the image to be acquired into (see member eVision.EMovingAverage.SrcImage).

NumberOfImages()

int eVision.EMovingAverage.NumberOfImages

(

self

)

Gets the number of images on which to integrate.

Reset()

None eVision.EMovingAverage.Reset

(

self

)

Restarts the average process as if no image had ever been handed to the eVision.EMovingAverage object.

Remarks:

The behavior is thus the same as after a eVision.EMovingAverage.SetSize operation.

SetSize() [1/2]

None eVision.EMovingAverage.SetSize	(		self,
		int	numberOfImages,
		int	imageWidth,
		int	imageHeight )

Initializes a moving average context with appropriate parameters.

Parameters

numberOfImages	Number of images on which to integrate. A power of 2 is recommended.
imageWidth	Image width.
imageHeight	Image height.

SetSize() [2/2]

None eVision.EMovingAverage.SetSize	(		self,
		int	numberOfImages,
		int	imageWidth,
		int	imageHeight,
		bool	internalAllocationScheme )

Initializes a moving average context with appropriate parameters.

Parameters

numberOfImages	Number of images on which to integrate. A power of 2 is recommended.
imageWidth	Image width.
imageHeight	Image height.
internalAllocationScheme	Buffer allocation scheme. When true, the moving average context provides the image to be acquired into (see member eVision.EMovingAverage.SrcImage).

SrcImage()

eVision.EImageBW8 | None eVision.EMovingAverage.SrcImage

(

self

)

Returns the image in which you must store the next image to be averaged.

Remarks:

This method may be used only when the buffer allocation scheme has been set to internal (see eVision.EMovingAverage.SetSize or eVision.EMovingAverage.__init__)
