#2. 3D sensors will unlock iPhone 8 with blazing fast speed. If reports are to be believed, you will be able to unlock your iPhone or quickly authenticate Apple Pay purchases in a “few hundred milliseconds.”

#3. Recent HomePod leaks have also revealed Face ID feature. As per reports, infrared sensors are reported to be used in iPhone 8's front-facing camera notch. They will enable the iPhone to scan faces at various angles.

#4. The three-dimensional face recognition is considered to achieve improved accuracy. With the use of 3D sensors, it immaculately captures information about the shape of a face.

#5. Three-dimensional data points from a face significantly enhance the precision of face recognition.

#6. Once the information has been captured, it identifies distinctive features like the contour of the eye sockets, nose, and chin on the surface of a face.

#7. The biggest advantage of 3D face recognition is that it doesn't get affected by changes in lighting like other techniques.

#8. It is also able to identify a face from different viewing angles like profile view.

#9. Sophisticated sensors play a major role in 3D research as it's able to accurately capture 3D face imagery. They function by projecting structured light onto a face.

#10. A new way to capture a 3D picture is by using three tracking cameras which focus on multiple angles. While one camera points at the front of the subject, the second one focuses on the side, and the third one points at an angle. They seamlessly work in sync with one another to track a subject's face with lightning fast speed.
