Configuring Caliper Properties
Threshold, which is represented in the display by two red lines.
Edges having a magnitude equal to or exceeding the Magnitude Threshold
receive a score of 1. Edges with values below the Magnitude Threshold receive a
score ranging from 0 to 0.999, according to a manually set magnitude con-
straint function.
The Magnitude Threshold value can be modified in the Advanced Parameters
section of the tool interface.
A Magnitude Constraint must be defined individually for each edge of an edge
pair configuration.
The following figure shows examples of two different setups for a magnitude
constraint function.
To set a Magnitude Constraint:
1. In the drop-down list above the Function Editor, select First Edge Mag-
nitude Constraint or Second Edge Magnitude Constraint.
If either edge does not have the Magnitude box checked, it will not be
shown in the drop-down list.
2. In the Function Editor, use the mouse to drag handles and set the mag-
nitude limits. See examples in the following figure.
Setting the Magnitude Constraint in the Function Editor
Position Constraint
Position constraints restrict the caliper’s search for edges to a specific zone of
the region of interest.
l It is possible to graphically set a position constraint function when the
approximate position of an edge is known beforehand. This is useful for
scoring an edge based on its offset from the expected position.
