Facial recognition is a technology for identifying an individual by using their facial features. These days, facial recognition systems are increasingly used in a diverse range of applications, from border control to smartphones. More recently, facial recognition technology has begun harnessing the power of artificial intelligence (AI). But what exactly is AI powered facial recognition?
What is AI facial recognition?
In simple terms, facial recognition technology refers to a set of algorithms that work to distinguish/identify people in static images or videos. However, this isn’t a new technology and in fact, it’s been around since the 1960s and Woody Bledsoe, Helen Chan Wolf and Charles Bisson are known as the pioneers of facial recognition technology. In the 1970s, facial recognition was advanced by including more markers to automate the recognition. However, these measurements and locations were manually computed and extremely labour consuming. Facial recognition technology has become increasingly innovative over the years. Early facial recognition relied on biometrics – for instance, pinpointing facial features in photographs, such as pupil centres or the distance between the eyes before ultimately processing the data through a computer to start the recognition. These days, however, AI-based software can quickly comb through databases to compare multiple faces simultaneously and detect faces in a particular scene. What’s better, the typical accuracy of an AI facial recognition is over 99.5%, which won’t be achieved by using only biometrics alone.
How Does AI Facial Recognition Work?
In order for AI face recognition to work, it needs to practice on photosets that are manually selected. On the other hand, Deep learning or a function of AI can mimic the processing power and pattern-creation capabilities of the human brain. Then these abilities are used for making decisions.
Once the photos (that have existing, hand-matched correlations to people) are available, AI facial recognition can work on data points of the human face. For instance, AI face scanners attempt to match the distance between the eyes, the height of the cheekbones, etc. and try to find any variations like the distance from the camera, variations of angles of the face and so on.
How is AI Facial Recognition Technology Used Today?
AI facial recognition has already been used in many industries for years. So, here are some of the common areas that AI facial recognition usually comes in handy.
- Airport boarding: Due to thousands of passers-by, Airport security should flow seamlessly, and airport security and efficiency are taken up a notch by using “smart gates” which is a combination of facial identification and liveliness checks.
- CCTV systems: CCTV cameras that feature AI facial recognition can detect faces day and night even if they have a beard, wear hats, glasses, or partial masking.
- Access control: AI facial recognition can replace fingerprint scanners and keycards by providing fast and secure entry to workplaces and apartment building.
- Healthcare: AI can heighten the quality of pain management procedures or tracks patients’ medication consumption.
- Smart devices: For example, AI facial recognition limits the need for run-of-the-mill passwords for mobile devices, improves anti-spoofing capabilities, etc.
AI facial recognition and COVID-19
AI facial recognition can provide additional safety security in times of COVID19. As contactless systems, facial recognition access control systems can reduce the risk of virus transmission in public buildings and apartments. Smart face scanners can even recognise people wearing masks as well as measuring body temperature for added safety and security.
Conclusion
As AI facial recognition technology matures, it provides many exciting applications for improving public safety and security. For example, smart access control systems have become widely available and increasingly affordable to individuals and organisations of all sizes. That being said, not all facial recognition systems are created equal. In order to provide the maximum benefits for your workplace or organisation, make sure to go for a reliable and efficient AI face scanner to bring your safety and security to new heights.
