FACIAL RECOGNITION


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



Facial recognition software has become increasingly popular in the past several years. It is used everywhere from airports, venues, shopping centers and even by law enforcement. While there are a few potential benefits to using the technology to prevent and solve crimes, there are many concerns about the privacy, safety and legislation regarding the use of the technology.




Facial recognition technology uses a database of photos, such as mugshots and driver's license photos to identify people in security photos and videos. It uses biometrics to map facial features and help verify identity through key features of the face. The most key feature is the geometry of a face such as the distance between a person's eyes and the distance from their forehead to their chin. This then creates what is called a "facial signature." It is a mathematical formula that is then compared to a database of known faces.




The main reason for concerns amongst citizens is the lack of federal regulations surrounding the use of facial recognition technology. Many are worried about how accurate the technology is and if there are biases and misinformation in these technologies. One issue, for example, is that the technology has been proven in multiple studies to be inaccurate at identifying people of color, especially black women.



Not only is this a concern with the possibility of misidentifying someone and leading to wrongful convictions, it can also be very damaging to our society by being abused by law enforcement for things like constant surveillance of the public.



Applications: -
  1.    Mobile platforms.
  2. Social Media
  3. ID Verification
  4.  Face ID Unlock

Advantages: -


·         Able to person mass identification as it does not require the cooperation of the test subject to work.

Disadvantages: -


·         Face recognition is less effective if facial expressions vary.


·        As compared to other biometric techniques, face recognition may not be most reliable and efficient.


·         Quality measures are very important in facial recognition systems
