Parameters

Name Type Range Default Description
inImageAvlNet.ImageImage to fit the circle to.
inFittingFieldAvlNet.CircleFittingFieldCircle fitting field.
inFittingFieldAlignmentAvlNet.CoordinateSystem2D?Adjusts the fitting field to the position of the inspected object. Default value: atl::NIL.
inScanCountint<3, INF>10The number of points that will be searched to estimate the position of the circle. Default value: 10.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSamplingParamsAvlNet.SamplingParamsParameters controlling the sampling process.
inRidgeScanParamsAvlNet.RidgeScanParamsRidgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f RidgeWidth: 5 RidgeMargin: 2 MinMagnitude: 5.0f RidgePolarity: Dark )Parameters controlling the ridge extraction process. Default value: RidgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f RidgeWidth: 5 RidgeMargin: 2 MinMagnitude: 5.0f RidgePolarity: Dark ).
inRidgeSelectionAvlNet.SelectionSelection mode of ridges.
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.
outRidgesSystem.Collections.Generic.IList<AvlNet.Ridge1D?>Found ridges.
outDeviationProfileAvlNet.INullable<AvlNet.Profile>Profile of distances between the actual circle points and the corresponding reference circle points. This parameter cannot be null.
outAlignedFittingFieldAvlNet.CircleFittingFieldFitting field used; in the image coordinate system.
outInliersSystem.Collections.Generic.IList<AvlNet.Point2D>Points matching the fitting Circle.
outBrightnessProfilesSystem.Collections.Generic.IList<AvlNet.Profile>Extracted image profiles.
