What Is A Facial Recognition System And What Is The Goal?

The facial recognition is a biometric solution that uses an automatic algorithm to verify or recognize the identity of a person based on physiological characteristics.

The facial recognition technology works from comparisons between the attributes of the face of the person to be identified and millions of individuals with similar characteristics contained in a huge database.

The objective of a facial recognition system is that given an image of an "unknown" face, or test image, it should find an image of the same face in a set of "known" images, or training images. The great added difficulty is to make this process possible in real time. Facial Recognition trainer, will identify the faces present in images or videos automatically.

It operates in two modes:

Face verification or authentication: compares an image of the face with another image with the face of which we want to know the identity.

Face Identification or Recognition - Compare the image of an unknown face with all the images of familiar faces found in the database to determine its identity.

2D and 3D facial recognition

The face of the person is a physical characteristic that allows the identification of the person in a unique and stable way. There are teams that capture the 2D pattern (projection on the plane) and equipment that captures the 3D pattern (volumetric description of the face).

2D facial recognition

2D facial recognition not distinguish whether what they are capturing is actually a face or a photograph of a face, therefore, in most access control applications do not offer a sufficient level of safety.

3D facial recognition

The terminals 3D face recognition include technology infrared combined with 3D , which is no longer possible to use masks or photographs to falsify the face of the person. 3D facial biometry allows very fast and secure contactless identification. If still you are not happy then you may think about the facility of TOT Key Note Speaker.

3D facial biometry for added security

The 3D equipment offer higher security and they need a real face and not a photograph to identify a user.One of the most important characteristics of facial recognition systems is the ability to identify the person without any contact. The ability for the user to be identified remotely makes them ideal for presence and access control applications in environments where direct contact is not the most ideal and may represent some problems either for hygiene reasons or for the simple made to wear gloves.

3D Facial Recognition

In recent years, the trend of three-dimensional facial recognition has increased, where 3D images are used both in training and in recognition. This technique allows capturing all the information about the shape of the face and the information will be used a posteriori to identify the characteristic features of the person's face: contour of the eyes, cheekbones, nose and chin and thus retaining the spatial information, a part of texture and depth.

To obtain 3D images it is necessary that the 3D sensor is very well calibrated and synchronized.
