Static is faster than relative segmentation because the gray levels
corresponding to the percentages do not have to be computed. Static
segmentation can test for absence of a feature in a scene, whereas relative
segmentation will always find a blob in the scene.
5 Adjust the parameters in the Search Parameter according to your
requirements.

In the Search Parameters part, define the values for the feature.
Area is expressed in mm
Perimeter is expressed in mm.
Circularity defines the circularity. A value of 1 means perfectly circular and
completely filled (no holes).
Elongation is the ratio of the feature's second moment of inertia about its
second principal axis to the feature's second moment of inertia about its first
principal axis.
Angle defines how the found item is sent to the controller.
• No Orientation means that the found item is sent to the controller with
angle 0 (zero).
• First Principal Axis means that the found item is sent down with the
angle around the first principal axis. The angle is relative to the x-axis
and can be ±90 degrees.
Use boundary box center defines if the position of a blob will be at the center
of its boundary box instead of at its center of mass.
No Blob On Edge defines if a blob connected to the edge of the search area
should be reported.
Use Inspection Levels defines if the found models should be classified. See
