• Major axis – minimum and maximum for the major axis of objects. Objects outside this
range are not counted. A zero in the maximum field means there is no maximum limit.
•
Minor axis – minimum and maximum for the minor axis of objects. Objects outside this
range are not counted. A zero in the maximum field means there is no maximum limit.
NOTE The minimums for Area, Major axis and Minor axis are initially set to 10% of
the objects first detected when you draw the Region. These may need adjusting,
depending on lighting or the range of defects. Objects smaller than the mini-
mum settings, or larger than the maximum settings will be ignored. A zero in the
maximum field means there is no maximum limit.
• Select – define the number of objects or defects reported:
Range – report all the objects in the range specified by Area, Major axis, and Minor axis,
Max – report only the one largest object in the range specified by Area, Major axis, and
Minor axis,
Min – report only the one smallest object in the range specified by Area, Major axis, and
Minor axis.
• Auto label position – puts the label (N1, N2) beside the Region in the display. Clear the check
box to move the label to another location (or with the Properties box closed, drag the label).
• Locator – makes the tool follow the Locator, and follow the part. Select a locator (by number)
to follow, or select “X” to disconnect the tool from the locator, or make the tool stay in a fixed
position in the image area.
• Channel – select a color class, or select “Brightness” for (monochrome) intensity.
• Reject touch – do not include objects that touch the outline edges of the Region you created.
• Show center point – displays a point at the center of each object found in the Region, and al-
lows you to use the point(s) in other measurements. Limited to 20 points maximum.
• Object type – “Bright” means identify and count bright objects on a dark background. “Dark”
means identify and count dark objects on a bright background. “Either” means find both bright
and dark objects.
• Light – type of light falling on the object or light variation across the Region. ”Variable” means
the light may vary across the object (left to right or top to bottom). Selecting ”Variable” turns
on ”local adaptive threshold” but is less sensitive to background variation. Selecting ”Uni-
form” turns on ”adaptive threshold” that is applied uniformly to the whole Region.
