Face recognition technology is being widely used in various businesses belonging to diverse industry verticals. The facial recognition system has received a lot of support from the people and businesses as well. AI face recognition is a powerful and disruptive form of technology for various fields.
What is the face recognition system?
- The face recognition system is one that involves the process of scanning an individual’s face and matching it to a database having various faces, to perfectly identify the same person’s face.
- Unlocking smartphones using facial recognition technology or biometric authentication of a person using the face while entering a premise are common examples where the facial recognition system is being used.
- The facial recognition system makes use of a technology that is able to match a human face from a digital image or video to a database of faces.
- Facial recognition technology makes use of a group of algorithms that work together to identify real people from static images or real (live) images in -video frames.
- When we talk about the history of face recognition, it started nearly 50 years ago when a group of researchers worked on using their computer for recognition of human faces.
- The facial recognition system delivers an accuracy of 99.5% in standard datasets.
How does the facial recognition system work?
- The sensors in the facial recognition system work by capturing a user’s face in 2D or 3D from a photo or video.
- Distances between the eyes, nose, mouth, and jaws are measured; the geometry of the user’s face.
- These distances are converted into a dataset.
- Each dataset consists of unique facial landmarks that distinguish a user’s face from the others.
- A facial signature is created (using a mathematical formula) which is unique to an individual.
- A user’s facial signature is compared with the other facial signatures that exist in the database.
- The facial signature is matched with an existing database until a successful match is found.
Reasons why facial recognition systems have become popular
- Authentication made easy and convenient
- Reduced operational costs
- Integration with other technologies possible without any hassles
- 24*7 functioning possible
- Eliminates the need for manual intervention
- Highly accurate, negligible chances of errors
- Enhanced security and surveillance
Applications of facial recognition
There are a wide range of applications of facial recognition. These include:
- Aid forensic investigations by identification of individuals in the CCTV footage.
- Facial recognition technology is used by social media platforms like Facebook to identify other Facebook members when tagged in a photo.
- Face ID as a biometric authentication introduced by Apple in the flagship iPhone X.
- Face identification can be used to detect notable changes in appearance in individuals suffering from diseases and infections.
- AI face recognition can also be used to track the students’ attendance in schools.
- Airports are making use of facial recognition systems to make the process of check-in and boarding flights easy and convenient.
- Face identification software makes it possible to find lost people and pets too.
- Records of patients can be stored conveniently and systematically in hospitals and other healthcare centers.
- Governments and security forces in various countries are making use of facial recognition technology to identify criminals and culprits who break the law.
Facial recognition system for Grizzly bears
- It is difficult to distinguish one grizzly bear from another due to the lack of proper distinguishable markers.
- Researchers have come up with BearID, an open-source software that enables scientists to differentiate between one grizzly bear from another and keeping a track of their populations.
- In the BearID project, the facial recognition system measures the distances between various facial features in a grizzly bear and compares them to an existing database.
Facial recognition system at the Atlanta Airport
- The facial recognition technology is being brought to the Hartsfield-Jackson Atlanta International Airport (ATL) by Delta Airlines, the Transportation Security Administration (TSA), and a travel tech company named Pangiam.
- According to this system, Delta SkyMiles members who make use of the Flying Delta app, and also have a TSA PreCheck Membership will be able to navigate the airport more effectively by simply looking at the camera to present their digital ID.
- This facial recognition system will make the process of check-in, bag drop, and security extremely convenient.
- It will reduce the time that passengers spend in the security checks and offer more time for exploring the different stores at the airport, for shopping, eating, and drinking.
The use of facial recognition systems is creating a tremendous impact on various industries. The day is not far off when we will use face identification for nearly all day-to-day activities that we do.
