Default value: EdgeScanParams ( ProfileInterpolation: Quadratic4 SmoothingStdDev: 1.0f MinMagnitude: 5.0f EdgeTransition: BrightToDark ).
inEdgeSelectionFilNet.SelectionSelection mode of edges.
inLocalBlindnessFilNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: ftl::NIL.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of edge points not found. Default value: 0.1f.
