magnitude constraint function.
The Magnitude Constraint is applied globally to all edges detected.
The following figure shows two different setups for a magnitude constraint func-
tion.
To set the Magnitude Constraint:
1. In the drop-down list above the function editor, select Magnitude Con-
straints.
2. In the Function Editor, use the mouse to drag handles and set the Mag-
nitude limits. See examples in the following figure.

Position Constraint
The Position constraint restricts the tool’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.
l Values in the Constraint Function Editor indicate relative distance in the
region of interest where 0.0 is the left-most position and 1.0 is the right-
most position.
To set the Position Constraint:
1. In the drop-down list above the function editor, select Position Con-
straints.
2. In the Function Editor, use the mouse to drag handles and set the Posi-
tion limits. See examples in the following figure.
