AddOnAnalysis
When a position has been defined, further analyses can be specified (if enabled
for the system). These can, for example, help differentiate very similar positions.
Click AddOn Analysis to specify the extra analyses.

Introduction
The standard analysis is the analysis alternative that you will use in the majority
of all cases. But sometimes, when the shape of the detail may vary within certain
ranges, it can be useful to do a blob analysis.
During identification of a position, the system analyzes the properties of each blob
found in the image and compares them with the corresponding property of the
teachin detail. The properties that are evaluated are area, perimeter, elongation
and compactness. The analyses of all properties except area can be deselected.
For all properties, an upper (Area max. deviation) and lower (Area min. deviation)
limit is specified as a percentage. The property requirements for the two positions
must be completely different in at least one aspect, otherwise a warning is displayed
to the user.
In many cases, it is sufficient to specify the area settings to identify details. The
area settings are therefore directly accessible on the user interface.
In some cases, these may need to be supplemented with perimeter, elongation
and compactness in order to differentiate the details better. These settings are
accessed by clicking on Advanced and described in
