Point Finder Guideline Offset The Guideline Offset is the offset from the tool Y-axis. The Guideline marker can be displaced along the X-axis. This marker acts as both a visual guide for positioning the tool and as a con- straint for the tool Search Mode. Properties Polarity Mode Polarity Mode 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 hypo- thesis. The available modes 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. Results Logging If enabled, the results of the tool will be logged to a file. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 599
