Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image to fit arc to.
inFittingMapAvlNet.ArcFittingMapInput fitting map.
inEdgeScanParamsAvlNet.EdgeScanParamsParameters controlling the edge extraction process.
inEdgeSelectionAvlNet.Selectionavl::Selection::BestSelection mode of edges. Default value: avl::Selection::Best.
inLocalBlindnessAvlNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of edge points not found. Default value: 0.1f.
inFittingMethodAvlNet.CircleFittingMethodAlgebraicTaubinMethod used to fit an arc. Default value: AlgebraicTaubin.
inOutlierSuppressionAvlNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: atl::NIL.
outArcAvlNet.Arc2D?Fitted arc or nothing if the fitting fails.
outEdgesSystem.Collections.Generic.IList<AvlNet.Edge1D?>Found edges.
outDeviationProfileAvlNet.INullable<AvlNet.Profile>Profile of distances between the actual arc points and the corresponding reference arc points. This parameter cannot be null.
outInliersSystem.Collections.Generic.IList<AvlNet.Point2D>Points matching the fitting arc.
outBrightnessProfilesSystem.Collections.Generic.IList<AvlNet.Profile>Extracted image profiles.
outResponseProfilesSystem.Collections.Generic.IList<AvlNet.Profile>Profiles of the edge (derivative) operator response.
