Threshold
In 1:N verification mode, the verification will only be successful when the
similarity between the acquired facial image and all the 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, the higher the rejection rate, and vice versa. The default
value of 75 is recommended.

Threshold
In 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, the higher the rejection rate, and vice versa. The default
value of 63 is recommended.
Face Enrollment

When the similarity between the acquired facial image and all the registered
facial templates is greater than this threshold, it indicates that the face has
already been registered.
