Parameters

Name Type Range Default Description
ioStateFilNet.CircleFittingState
inImageFilNet.ImageImage to fit the circle to.
inFittingFieldFilNet.CircleFittingFieldCircle fitting field.
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.
inImageInterpolationFilNet.InterpolationMethodBilinearInterpolation method used for extraction of image pixel values. Default value: Bilinear.
inRidgeScanParamsFilNet.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 ).
inRidgeSelectionFilNet.SelectionSelection mode of ridges.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of ridge points not found. Default value: 0.1f.
inFittingMethodFilNet.CircleFittingMethodAlgebraicTaubinMethod used to fit a circle. Default value: AlgebraicTaubin.
outCircleFilNet.Circle2D?Fitted circle or nothing if the fitting fails.
outRidgesFilNet.NullableRef<System.Collections.Generic.List<FilNet.Ridge1D?>>Found ridges. Can be null to skip this parameter calculation.
outDeviationProfileFilNet.NullableRef<FilNet.NullableRef<FilNet.Profile>>Profile of distances between the actual circle points and the corresponding reference circle points. Can be null to skip this parameter calculation.
outAlignedFittingFieldFilNet.NullableValue<FilNet.CircleFittingField>Fitting field used; in the image coordinate system. Can be null to skip this parameter calculation.
outInliersFilNet.NullableRef<System.Collections.Generic.List<FilNet.Point2D>>Points matching the fitting Circle. Can be null to skip this parameter calculation.
diagScanSegmentsSystem.Collections.Generic.IList<FilNet.Segment2D>Segments along which the scans were run.
