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.
Minimum Face Size:
It sets the minimum face size required for facial
registration and comparison.
If the minimum size of the captured image is smaller than the set value,
then it will be filtered off and not recognized as a face.
This value can also be interpreted as the face comparison distance. The
farther the individual is, the smaller the face, and the smaller number of
pixels of the face obtained by the algorithm. Therefore, adjusting this
parameter can adjust the farthest comparison distance of faces. When
the value is 0, the face comparison distance is not limited.
LED Light Trigger Threshold:
This value controls the turning on and
off of the LED light. The larger the value, the LED light will turn on or off
more frequently.
