Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inStdDevXfloat<0.0f, INF>3.0fSmoothing standard deviation (horizontal). Default value: 3.0f.
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
inMinBlobAreaint<0, INF>1Minimal area of a ridge blob. Default value: 1.
outRidgeRegionAvlNet.Region
