Facial recognition system


A facial recognition system is a technology capable of identifying or verifying a person from a digital image or a video frame from a video source. There are multiple methods in which facial recognition systems work, but in general, they work by comparing selected facial features from given image with faces within a database. It is also described as a Biometric Artificial Intelligence based application that can uniquely identify a person by analyzing patterns based on the person’s facial textures and shape.

While initially a form of computer application, it has seen wider uses in recent times on mobile platforms and in other forms of technology, such as robotics. It is typically used as access control in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems. Although the accuracy of facial recognition system as a biometric technology is lower than iris recognition and fingerprint recognition, it is widely adopted due to its contactless and non-invasive process. Recently, it has also become popular as a commercial identification and marketing tool. Other applications include advanced human-computer interaction, video surveillance, automatic indexing of images, and video database, among others.

  • Sampling: using cameras or devices with image acquisition function.
  • Processing: handling samples to collect data and store in the system.
  • Comparison: the data obtained is compared with the previously analyzed sample data.
  • Results: from the machine comparison index give matching results or not.

Every time the object is in range of the camera, the new system starts its identification process. Whether the object is moving or stationary, the machine can still detect and detect faces and use algorithms to produce results.


  • The system works with large numbers of people in a short time.
  • The subject does not need to impact or touch anything to be identified.


  • Attendance control for businesses with large numbers of people with fast response speed.
  • Notify cases of illegal infringement.
  • Create restricted access groups in an area.
  • Allow extracting time data, more convenient to manage.


  • Airports (terminals, customs control areas), seaports
  • Stadium, subway station
