AVL.DetectRidges_AsPaths Method

Extracts subpixel-precise paths that represent bright or dark thin lines.

Syntax

public static void DetectRidges_AsPaths(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	float inStdDevX,
	float? inStdDevY,
	float inRidgeThreshold,
	float inRidgeHysteresis,
	AvlNet.Polarity inPolarity,
	out AvlNet.Path[] outRidges
)

Parameters

	Name	Type	Range	Default	Description
	inImage	AvlNet.Image			Input image.
	inRoi	AvlNet.Region			Region of interest. Default value: atl::NIL, or null.
	inStdDevX	float	<0.0f, INF>	3.0f	Smoothing standard deviation (horizontal). Default value: 3.0f.
	inStdDevY	float?	<0.0f, INF>		Smoothing standard deviation (vertical, or Auto = horizontal). Default value: atl::NIL, or null.
	inRidgeThreshold	float	<0.0f, INF>	5.0f	Sufficient ridge strength; ridges of that strength will always be detected. Default value: 5.0f.
	inRidgeHysteresis	float	<0.0f, INF>	4.0f	Value by which the ridge threshold is decreased for ridge points neighboring with sufficiently strong edges. Default value: 4.0f.
	inPolarity	AvlNet.Polarity
	outRidges	AvlNet.Path

Remarks
