Configuring Edge Locator Properties

Magnitude Constraint

The Magnitude constraint is based on edge values relative to the Magnitude

Threshold. Edges having a magnitude equal to or exceeding the Magnitude

Threshold are given 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 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.

Setting the Magnitude Constraint in the Function Editor

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:
