AVL.GradientDirAndPresenceImage(AvlNet.Image, AvlNet.GradientMaskOperator, float, AvlNet.Image)

Computes an image of gradient directions mapped to the range from 1 to 255. Zero means "no edge".

Syntax

public static void GradientDirAndPresenceImage(
	AvlNet.Image inImage,
	AvlNet.GradientMaskOperator inOperator,
	float inEdgeThreshold,
	out AvlNet.Image outDirectionsImage
)

Parameters

inImage

Type: AvlNet.Image
Input image

inOperator

Type: AvlNet.GradientMaskOperator
Defines how the gradient is computed

inEdgeThreshold

Type: System.Single
Minimum edge magnitude (other pixels will be set to 0)

outDirectionsImage

Type: AvlNet.Image

Remarks

See full override for more details.
