Basically, facial recognition can be understood as a resource to identify or confirm an individual's identity from a technological system and can be used to identify photos, videos or applications in real time. Recognition belongs to the category of biometric security along with other forms, such as voice recognition, fingerprint recognition, among others.
Although each technology has its own particularities, in general, facial recognition works with the following steps:
Face detection – This occurs by detecting a camera, which will locate the image of a face.
Facial analysis – after detection, the captured image is analyzed venezuela mobile database using software that reads the geometry of the face, such as the distance between the eyes, depth of the eye sockets, distance between the forehead and chin, shape of the cheekbones, contour of the lips, among other aspects. In general, facial recognition technologies work with 2D images to match them with public or database photos.
Image conversion – With capture and analysis, it is possible to transform analog information (face) into sets of digital information (data). To understand, just imagine that the analysis of the face is transformed into a mathematical formula, in which a numerical code is called a facial impression.
Correspondence – After collecting all the data, it is possible to search for matches in databases that have cross-references.
The benefits of facial recognition
In addition to the benefits already mentioned, which speed up people's daily lives, such as unlocking smartphones, there are a number of advantages to using facial recognition. They are:
Public safety
Facial recognition can help identify criminals and terrorists, for example. It also contributes to reducing crime, as its implementation can facilitate tracking and even inhibit crime, especially when it comes to petty crimes.
