Figure 11. Successful recognition
Follow the same procedure to add additional faces into the system.
4.2 Deregistering a face
Similarly to the registration button discussed in the previous section, pressing and releasing the SW2 button (located at the back
of the kit) triggers a manual de-registration, which removes the next recognized face from the kit’s internal face database.
Figure 12. Manual deregistration button
The speaker plays an audio message, confirming that the de-registration started. During the face de-registration process, the
“Deregistering” message appears in green at the top of the screen and a red bounding box appears to help you align your face.
A timeout counter represented by a blue bar starts to count down.
To de-register your face, look straight-on to the camera and align your face in the bounding box presented by the UI.
