public static void DetectRidges_AsPaths
(
	AvlNet.Image inImage,
	NullableRef<AvlNet.Region> inRoi,
	float inStdDevX,

Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inRoiAvlNet.NullableRef<AvlNet.Region>Region of interest. Default value: atl::NIL.
inStdDevXfloat<0.0f, INF>3.0fSmoothing standard deviation (horizontal). Default value: 3.0f.
inStdDevYfloat?<0.0f, INF>Smoothing standard deviation (vertical, or Auto = horizontal). Default value: atl::NIL.
inRidgeThresholdfloat<0.0f, INF>5.0fSufficient ridge strength; ridges of that strength will always be detected. Default value: 5.0f.
inRidgeHysteresisfloat<0.0f, INF>4.0fValue by which the ridge threshold is decreased for ridge points neighboring with sufficiently strong edges. Default value: 4.0f.
inPolarityAvlNet.Polarity
