Banner PresencePLUS Pro COLOR—PROII Camera - Manual (Page 168)

The minimum and maximum object width affects both objects and spaces between objects. Minimum object width
can filter out objects and spaces.
Object Tool Results
The Results field returns the following:
• The position of the object midpoint. The origin (0,0) is the upper-left corner of the screen.
• A Select Object Number field for selecting an object to analyze.
• Total number of Bright, Dark, or All objects (depending on the Bright/Dark option in effect.
• Distance between the edges of the current object.
Graph Tab
When Edge Strength is selected, the Graph tab appears on the tool window. The graph for the Input tab overlays both
the edge strength graph and the edge profile. In the Graph tab, the edge profile graph and the edge strength graph are
separated for easier viewing.
The top graph, Edge Profile, represents the absolute gray scale level across the Edge tool.
The bottom graph, Edge Strength, represents the change in gray scale along the Edge tool.
Edge Strength detects an edge when the rate of change (solid red line on the screen) crosses the selected intensity
change amount (dashed green lines on the screen).
A bright-to-dark transition has a negative edge strength value, and a dark-to-bright transition has a positive edge strength
value. When the Edge Strength level is adjusted, both the negative and positive lines will adjust together.
