AVL.DifferenceOfGaussians Method

Applies difference of Gaussians on an image, i.e. computes difference of two Gaussian smoothed images.

Syntax

public static void DifferenceOfGaussians(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	float inStdDev,
	float inStdDevRatio,
	float inKernelRelativeSize,
	float inScale,
	out AvlNet.Image outImage,
	out AvlNet.Profile diagKernelShape
)

Parameters

	Name	Type	Range	Default	Description
	inImage	AvlNet.Image			Input image.
	inRoi	AvlNet.Region			Range of output pixels to be computed. Default value: atl::NIL, or null.
	inStdDev	float	<0.0f, INF>	3.0f	Smoothing standard deviation for the smaller kernel. Default value: 3.0f.
	inStdDevRatio	float	<1.0f, INF>	1.6f	Defines how many times larger is the second kernel. Default value: 1.6f.
	inKernelRelativeSize	float	<0.0f, 3.0f>	3.0f	A multiple of the standard deviation determining the size of the kernel. Default value: 3.0f.
	inScale	float		1.0f	Output image scaling factor. Default value: 1.0f.
	outImage	AvlNet.Image			Output image.
	diagKernelShape	AvlNet.Profile			Middle row of the kernel being used.
