Sensitivity When
Finding
Indicates sensitivity to noise in image while looking for the model. Higher
settings allow rougher edges and causes more thorough and longer
searching.

Initial Search Reso-
lution
Half Resolution: This setting can be used with most general purpose
applications. The tool runs faster with this setting.
Full Resolution: This setting can be helpful in applications where the
edges are packed close together or
the search area is small. The tool runs slower with this setting but it is
more reliable, so it should mainly be used in application that demand full
resolution matching or that can tolerate slower execution, such as those
with a small search area.
Output Name What it is
Found Match True when a model with a score greater than the Minimum Match Score
is found
Output Best Origin The model’s origin relative to the input tool origin
Output Best Origin
Relative to RWC
The model’s origin in Real World Coordinates. Use this value when the
Origin needs to be relative to the image for display or it needs to be
linked as another tool’s origin
Output Best Score The best match score greater than the Minimum Match Score (1 to 100)
Output Origin List List of Origins relative to the input tool origin
