Face Detection

The picture of the targeted face is detected/captured from a video or photo.

Face Analysis

The system will read the geometry of the targeted face. After that, it will match the picture with those in a database. The system examines different nodal points of a human face, such as space between eyes, the shape of cheekbones, etc.

Converting an Image to Data

In the 3rd step, face analysis is then turned into a numerical code known as a face print. Every person has a unique face print.

Finding a Match

In the last step, the face print or code is compared against other face prints from a database. The database usually contains pictures with identification, which can be compared.

How Accurate is The System

Can a face recognition system be fooled? A lot of people have this concern. Over the years, face recognition technology has improved considerably. The top identification algorithm has an error rate of only 0.8%. So we can say in any condition, a facial recognition system can achieve an accuracy score as high as 99.97%.

Uses of A Facial Recognition Solution in Different Industries

Facial Recognition
A biometric face recognition solution is used to identify and authenticate an individual with the help of verifiable data, specific to that person. At present, facial recognition technology has been used in a variety of places and by a variety of industries. Check out a few major examples below.

Finding Missing Persons

In many countries, face recognition technology is being used to locate missing children and victims of human trafficking. If missing individuals are added to a database, it can be more comfortable for law enforcement agencies to recognize and find the missing people.
