1:N Threshold
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 the
higher the rejection rate, and vice versa. It is
recommended to set the default value of 47.
1:1 Threshold
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 0 to 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.
