Interface of the Sample#

This section provides information on available features of the Face SDK VideoEngine JS demo that demonstrates face detection and tracking, as well as active liveness estimation.

  • The left side of the screen displays the video stream from the webcam (Stream).
  • To start the Active Liveness check, press the Start button. During the processing, a progress bar and the phrase "Wait, detection is in progress ..." are displayed above the window with the video stream. If at least one blink is made during processing and the head is turned at least once, a face is considered to belong to a real person.
  • The best shot of the face is displayed to the right of the video stream. If the face is not positioned correctly, the browser will display hints during processing. For example, "Please turn your head up", "Please come closer to the camera", etc.
  • To stop the Active Liveness check, press the Stop button.
  • To clear the received data, press the Clear button.
