4.7 Job parameter
An additional sub-ROI is trained:
"Find" job
If the "Job" parameter is set to the value
"Find", the following quality values are
obtained:
Main ROI: 98.7%
•
Additional sub-ROI: 90.5%
•
Even a value of 90.5% is too unreliable
to be able to set the quality limit here.
"Identify" job.
The "Job" parameter is now set to
"Identify" for the additional sub-ROI. The
following result is then achieved:
Quality value of the additional sub-ROI:
69.3%
Changes can now no longer be reliably
detected with an increased quality limit.
