Exploring the Superiority of Facial Recognition over 2D: A Comprehensive Guide

Facial recognition is a technology that maps, identifies, or verifies an individual’s facial features. It creates a unique numerical code, a faceprint, stored in face recognition databases. When a photo is entered for verification, the matching faceprint is found in the stored pictures. Facia uses a 3D face scanner for face identity verification, which is secure and easy to use. Three standard facial recognition methods are traditional face recognition, 3D face scan, and biometric face recognition. Traditional face recognition uses a photograph to identify the person, a 3D face scan captures the person’s picture in real-time, and biometric face recognition analyzes unique face characteristics for identity verification.

Why is 3D facial recognition superior to 2D facial recognition?

3D face recognition outperforms 2D due to its ability to perform pattern recognition, capturing and analyzing the depth of the human face. This method uses a 3D face model, allowing it to take advantage of the human face’s 3D geometry, ensuring robust recognition despite changing lighting conditions, diverse facial expressions, and varying head angles. Artificial intelligence plays a central role in this method, conducting pattern analysis on the 3D facial data to ensure robust recognition despite pose variations and shifts in illumination.

How does facial recognition work?

Facial recognition technology uses AI and biometrics to identify human faces. It maps facial features from a photograph or video and compares them with a database of known faces to find a match. This method helps verify a person’s identity but also raises privacy issues. The software presents at least one video or image of an individual’s face, scanning it to create a map of their facial features called a facial signature. Facial recognition systems compare this signature to their database, which contains millions to billions of images. The system determines if the signature matches anything in the database, calculates an accuracy score, or provides alternatives.

3D detection of faces

3D facial recognition technology uses sensors or face scanners to capture face shapes accurately, ensuring precision even in darkness. Unlike traditional methods, this technology is not affected by lighting and can perceive an objective from various angles. Face ID technology, like the iPhone X and later versions, relies on 3D facial recognition for face identification.


  • 3D face images captured using cameras or phones.
  • Alignment: Face angle, size, and position determined by software.
  • Measurement: The face shape is measured by the scanner.
  • Representation: System template converted into code.


  • Database search for a match for the converted template.
  • 3D pictures can be matched without additional steps.
  • 2D pictures converted using calculation.


  • Software can either identify or verify the user based on the situation.
  • Verification can match the scan to a valid identity picture or identify an individual by comparing it with all database images.

Simplicity of Online Face Scanner

Face scanners are online devices that enable users to verify their identity without complicated hardware, making the process quick, easy, and secure. They can be used for social media logins or online banking, providing a virtual security guard with VIP account access.
