StandardDeviationImage

Creates image of pixels' local standard deviations.

Header:	AVL.h

Syntax

void avl::StandardDeviationImage
(
	const avl::Image& inImage,
	atl::Optional<const avl::Region&> inRoi,
	atl::Optional<const avl::Region&> inSourceRoi,
	const int inKernelRadius,
	avl::Image& outStdDevImage
)

void StandardDeviationImage
(
	Image inImage,
	Region? inRoi,
	Region? inSourceRoi,
	int inKernelRadius,
	out Image outStdDevImage
)

Parameters

Name	Type	Range	Default	Description
inImage	const Image&			Input image.
inRoi	Optional<const Region&>		NIL	Region of Interest.
inSourceRoi	Optional<const Region&>		NIL	Range of inImage pixels to be read
inKernelRadius	const int	1 - 40	4	Radius of square kernel (width and height are 2r+1).
outStdDevImage	Image&			Resulting image.

Requirements

For input inImage only pixel formats are supported: uint8, int8, uint16, int16, real.
