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 the higher the rejection rate, and vice versa. It is
recommended to set the default value of 47.
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 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.
Face Rotation Angle
It is the rotation angle tolerance of a face for facial template registration and
comparison.
If a face’s rotation 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.
Image Quality
It is the image quality for facial registration and comparison. The higher the
value, the clearer image is required.
