Parameters

Name Type Range Default Description
ioStateAvlNet.ArcFittingState
inImageAvlNet.ImageInput image to fit arc to.
inFittingFieldAvlNet.ArcFittingFieldArc fitting field.
inScanCountint<3, INF>10The number of points that will be searched to estimate the position of the arc. Default value: 10.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inImageInterpolationAvlNet.InterpolationMethodBilinearInterpolation method used for extraction of image pixel values. Default value: Bilinear.
inStripeScanParamsAvlNet.StripeScanParamsStripeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Dark MinStripeWidth: 0.0f MaxStripeWidth: Nil )Parameters controlling the stripe extraction process. Default value: StripeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 0.6f MinMagnitude: 5.0f MaxInnerEdgeMagnitude: Nil StripePolarity: Dark MinStripeWidth: 0.0f MaxStripeWidth: Nil ).
inStripeSelectionAvlNet.SelectionSelection mode of stripe.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of stripe points not found. Default value: 0.1f.
inFittingMethodAvlNet.CircleFittingMethodAlgebraicTaubinMethod used to fit an arc. Default value: AlgebraicTaubin.
outArcAvlNet.Arc2D?Fitted arc in the middle of found stripe.
outInnerArcAvlNet.Arc2D?Fitted inner arc.
outOuterArcAvlNet.Arc2D?Fitted outer arc.
outStripesAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.NullableRef<AvlNet.Stripe1D>>>Found stripes. Can be null to skip this parameter calculation.
