Parameters

Name Type Range Default Description
inImageAvlNet.ImageImage to fit segment to.
inFittingFieldAvlNet.SegmentFittingFieldSegment 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 segment. Default value: 10.
inScanWidthint<1, INF>5The width of each scan field (in pixels). Default value: 5.
inSamplingParamsAvlNet.SamplingParamsParameters controlling the sampling process.
inEdgeScanParamsAvlNet.EdgeScanParamsEdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: BrightToDark )Parameters controlling the edge extraction process. Default value: EdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: BrightToDark ).
inEdgeSelectionAvlNet.SelectionSelection mode of edges.
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.
inOutlierSuppressionAvlNet.LineMEstimator?Selects a method for ignoring incorrectly detected points. Default value: atl::NIL.
outSegmentAvlNet.Segment2D?Fitted segment or nothing if the fitting fails.
outEdgesAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Edge1D?>>Found edges. Can be null to skip this parameter calculation.
outDeviationProfileAvlNet.NullableRef<AvlNet.NullableRef<AvlNet.Profile>>Profile of distances between the actual segment points and the corresponding reference segment points. Can be null to skip this parameter calculation.
outAlignedFittingFieldAvlNet.NullableValue<AvlNet.SegmentFittingField>Fitting field used; in the image coordinate system. Can be null to skip this parameter calculation.
outInliersAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Point2D>>Points matching the fitting segment. 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 edge (derivative) operator response. Can be null to skip this parameter calculation.
