All You Need to Know about Face Recognition

Face Recognition

What is Face Recognition Technology?

Face recognition systems will use technologies that will ensure you will identify a person form a video, digital image, or more. They will work by comparing the selected face and then comparing it to the stored faces in the database and will either return positive or negative feedback. They will work like applications, and in recent times there is the development of mobile apps that will achieve this. Face recognition will use in schools, defense systems, and other application areas in our areas today. Ideally, the process of face recognition is in two steps. The first step will involve extraction and selection. And then, the second step is the classification of various objects.

Techniques for face acquisition

Let’s discuss various methods of facilitating face recognition.

Face Recognition

Traditional methods

In traditional recognition methods, the algorithms will identify any facial features by extracting features such as landmarks from an image of the person’s face. For example, developers will develop an algorithm that will analyze the relative position, size, and shape of the eyes. These features will then use search for other images with matching features. Recognition algorithms will then divide into two main approaches that are geometric. It will look looks at distinguishing features based models

Dimensional recognition

3D face recognition technology will feature 3D sensors to capture information about the shape of a face. This information then applies when identifying distinctive features on the surface of a look. They will include distinct features such as the contour of the eye sockets, nose, and chin.

Skin texture analysis

Skin texture analysis is another emerging trend. Also, it will use the visible attributes of the skin, as captured by standard digital or scanned images. These techniques, called Skin Texture Analysis, turns the unique lines, patterns, and spots apparent in a person’s skin into a mathematical space.

Application of face recognition

Face Recognition

Social media

Some social media will apply face recognition techniques to ensure that it will provide only the legitimate users will log in into their respective accounts such as Facebook, Snapchat, and more.

ID verification

The primary use of facial recognition is to identify the user and complement the use of ID verification services. Many companies and institutions are working in the market now to provide these services to banks, military barracks, institutions and many more

Face ID

Some companies such as Apple have recently introduced the Face ID on the flagship iPhone X, for example, has a biometric authentication successor to the Touch ID, a fingerprint-based Mechanism. The Face ID mechanism has a facial recognition sensor.

Below are various most frequently asked questions about face recognition technology

What is the purpose of face recognition technology?

Facial recognition technology will use biometric application software applications that are capable of uniquely identifying an individual and verifying a person by comparing and analyzing patterns based on the person’s facial contours that are usually in a stored database. Facial recognition is commonly used for security purposes, though there is increasing interest in other areas of use of this technology, for example, is social media

Does face recognition violate someone’s privacy?

Yes, to some extent, face recognition techniques will violate one’s privacy. The most significant disadvantage for facial recognition technology in most people’s opinions is the threat to an individual’s privacy. For example, several cities in the united states have considered or will ban real-time facial recognition Due to public demand and surveillance use by law enforcement. These cities include Massachusetts, Cambridge, and many other cities.

Face Recognition

Are there face recognition Apps?

Yes, there are face recognition apps in the market today. Companies such as Clearview AI has devised a groundbreaking and first facial recognition application. You will take a picture of a person, and then upload it over the internet and get to see all the public photos of that person. Along with links to where those photos appeared and probably the location they last appeared.

How will cameras recognize faces?

It is easy for a camera to detect your face easily because individual faces will have some easily recognizable and identifiable features that any smart cameras can lock on to. For example, a nose, pair of eyes, and a mouth. By a camera being able to detect a face in the scene, the camera will solely concentrate its autofocus on that person’s face to ensure it is the primary subject in focus within the image.

What kind of data will face recognition system use?

Facial recognition devices and applications will use a database of already stored photos. For example, Drivers License, and mugshots to identify people in security photos and videos. It will use biometrics to map facial features and help verify the identity through the key elements of the face such as the eyes, nose or the mouth


The world is advancing in technology, and the emergence of face recognition technology is one of the critical areas. The face recognition technology is primarily for security purposes. One will quickly identify one in case of a crime scene by comparing their image to the ones stored in a database. The technology is also suitable for tracing the lost people. One’s photo is posted, and google, for example, will compare with the billions of pictures available in their database. The face recognition technology is also featuring in banks and social media platforms.
