Item Description
1:N Threshold
Value
Under 1:N verification mode, the verification will only be successful when the
similarity between the acquired facial image and all registered facial templates
is greater than the set value.
The valid value ranges from 0 to 100. The higher the thresholds, the lower the
misjudgement rate and higher the rejection rate, and vice versa. The default
value of 75 is recommended.
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 facial templates enrolled in
the device is greater than the set value.
The valid value ranges from 0 to 100. The higher the thresholds, the lower the
misjudgement rate and higher the rejection rate, and vice versa. The default
value of 63 is recommended.
Face Enrollment
Threshold
During face enrolment, 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 (top to bottom and vice-versa) angle tolerance of a face for facial
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 and no registration or comparison interface will be
triggered.
