Parameters

Name Type Range Default Description
inImageAvlNet.ImageImage to fit the circle to.
inFittingMapAvlNet.CircleFittingMapInput fitting map.
inRidgeScanParamsAvlNet.RidgeScanParamsParameters controlling the ridge extraction process.
inRidgeSelectionAvlNet.Selectionavl::Selection::BestSelection mode of ridges. Default value: avl::Selection::Best.
inLocalBlindnessAvlNet.LocalBlindness?Defines conditions in which weaker ridges can be detected in the vicinity of stronger ridges. Default value: atl::NIL.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of ridge points not found. Default value: 0.1f.
inFittingMethodAvlNet.CircleFittingMethodAlgebraicTaubinMethod used to fit a circle. Default value: AlgebraicTaubin.
inOutlierSuppressionAvlNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: atl::NIL.
outCircleAvlNet.Circle2D?Fitted circle or nothing if the fitting fails.
outRidgesAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Ridge1D?>>Found ridges. Can be null to skip this parameter calculation.
outDeviationProfileAvlNet.NullableRef<AvlNet.NullableRef<AvlNet.Profile>>Profile of distances between the actual circle points and the corresponding reference circle points. Can be null to skip this parameter calculation.
outInliersAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Point2D>>Points matching the fitting Circle. Can be null to skip this parameter calculation.
outBrightnessProfilesAvlNet.NullableRef<AvlNet.SafeList<AvlNet.Profile>>Extracted image profiles. Can be null to skip this parameter calculation.
outResponseProfilesAvlNet.NullableRef<AvlNet.SafeList<AvlNet.Profile>>Profiles of the ridge operator response. Can be null to skip this parameter calculation.
