Configuring Point Finder Properties
The Properties section of the Point Finder tool interface provides access to Point Finder param-
eters and properties.
Polarity Mode
PolarityMode sets the mode that will apply to the search for entities. Polarity
identifies the change in grey-level values along the tool X axis, in the positive
direction.
The available modes are
l Dark To Light: The Point Finder searches only for point instances occur-
ring at a dark to light transition in grey-level values.
l Light To Dark: The Point Finder searches only for point instances occur-
ring at a light to dark transition in grey-level values.
l Either: The Point Finder searches only for point instances occurring
either at a light to dark or dark to light transition in grey-level values.
This mode will increase processing time.
l
Don’t Care: The Point Finder searches only for point instances occurring
at any transition in grey-level values, including reversals in contrast, for
example, on an unevenly colored background.
Search Mode
Search Mode sets the mode used by the tool to generate and select a hypoth-
esis.
The available mode are:
l
Point Closest To Guideline: Selects the point hypothesis closest to the
Guideline.
l
Point With Maximum Negative X Offset: Selects the point hypothesis
closest to the region of interest boundary that is at maximum negative X
offset.
l Point With Maximum Positive X Offset: Selects the point hypothesis
closest to the region of interest boundary that is at maximum positive X
offset.
Region of Interest (ROI)
The region of interest is the area in which the tool carries out its process. Most tool position
parameters can be set through the region of interest section of the tool interface. The fol-
lowing parameters define the tool region of interest.
