AVL.GradientImage Method

Computes a gradient image with smoothing operator of any size. The output pixels are signed.

Syntax

public static void GradientImage(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	AvlNet.GradientOperator inOperator,
	float inStdDevX,
	float? inStdDevY,
	out AvlNet.Image outGradientImage,
	out AvlNet.Image diagGradientDirections
)

Parameters

	Name	Type	Range	Default	Description
	inImage	AvlNet.Image			Input image.
	inRoi	AvlNet.Region			Range of outGradientImage pixels to be computed. Default value: atl::NIL, or null.
	inOperator	AvlNet.GradientOperator			Defines how the gradient is computed.
	inStdDevX	float	<0.0f, INF>	2.0f	Horizontal smoothing standard deviation. Default value: 2.0f.
	inStdDevY	float?	<0.0f, INF>		Vertical smoothing standard deviation. Default value: atl::NIL, or null.
	outGradientImage	AvlNet.Image			Gradients of the image.
	diagGradientDirections	AvlNet.Image			Gradient directions presented in a human readable format.
