ImageDifference_Deprecated

Header:	FIL.h
Namespace:	fil

Measures dissimilarity between two images.

Syntax

void fil::ImageDifference_Deprecated
(
	const fil::Image& inImage,
	const fil::Image& inPatternImage,
	ftl::Optional<const fil::Region&> inRoi,
	fil::DistanceMeasure::Type inDistanceMeasure,
	float& outDifference
)

Parameters

Name	Type	Default	Description
inImage	const Image&		Input image
inPatternImage	const Image&		Pattern to be compared with input image
inRoi	Optional<const Region&>	NIL	Range of pixels to be processed
inDistanceMeasure	DistanceMeasure::Type		Measure of distance
outDifference	float&		Value of difference between pattern and image

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: UINT8 (for inDistanceMeasure = MeanError).

This operation is optimized for SSE3 technology for pixels of types: UINT16 (for inDistanceMeasure = MeanError), UINT8 (for inDistanceMeasure = MeanSquaredError), REAL.

This operation is optimized for SSE4 technology for pixels of types: INT16, UINT16 (for inDistanceMeasure = MeanSquaredError).

This operation supports automatic parallelization for multicore and multiprocessor systems.
