1:1 Threshold Value
Under 1:1 verification mode, the verification will
only be successful when the similarity between
the acquired facial image and the user’s facial
templates enrolled in the device is greater than
the set value.
The valid value ranges from 0to 100. The higher
the thresholds, the lower the misjudgement rate
and the higher the rejection rate, and vice versa.
It is recommended to set the default value of 63.
Face Enrollment
Threshold
During face enrollment, 1:N comparison is used
to determine whether the user has already
registered before.
When the similarity between the acquired facial
image and all registered facial templates is
greater than the set threshold, it indicates that
the face has already been registered.
Face Pitch Angle
It is the pitch angle tolerance of a face for facial
template registration and comparison.
If a face’s pitch angle exceeds the set value, it will
be filtered by the algorithm, i.e., ignored by the
terminal thus no registration and comparison
interface will be triggered.
