Face Reading with AI (Artificial Intelligence)


Assistant Professor - Department of Information Technology Kalinga University, New Raipur


In the present circumstances, face distinction has become one of the best technology for computer vision. Facial recognition is always a very difficult task in computer vision, lighting, pose, and facial expression. Face recognition tracks target objects in live video images captured by a video camera. In simple words, it is an automatic identification system application for a person from a still image or video. This application is based on face detection, feature extraction, and recognition algorithms that automatically detect a human face when the person is in front of the camera to know him. We used the KLT Algorithm, Viola-Jones a face detection algorithm that detects a human face using a cascade classifier, but the camera constantly detects the face of each image, PCA algorithm for feature selection. We use a combination of the model to match the geometric shape features of the human face.

What is Face Reading?

Face reading involves identifying features and expressions on a human face. In the digital context, the term is often used synonymously with facial analysis, sentiment analysis, facial expression recognition, and emotion recognition. Using artificial intelligence, computer software can read and analyze facial features. This forms the first step in facial recognition and also allows the software to recognize human emotions in real-time.

How does Face Reading work?

With digital face reading, the camera is used to take pictures that are transmitted to the Face Reading software application. The application then processes the data to detect faces and facial features (landmarks) and to identify expressions. The six basic expressions that can be detected are happiness, sadness, anger, surprise, fear, and disgust.

Artificial intelligence for face reading 

Face Reading technology is based on AI. Generally speaking, AI algorithms learn to recognize facial features and expressions by training on large data sets and creating templates. When analyzing a specific face, Face Reading software compares an image of a specific face to templates created by algorithms to identify facial features and determine predominant emotions.

When deep learning methods are used to train the AI ​​algorithms used in Face Reading software, the accuracy of the software increases.

Why is Face Reading technology important?

Face Reading makes it possible to accurately and unbiasedly observe human emotions. For example, when conducting market research, businesses can use Face Reading software to record and interpret audience reactions to products or advertisements. This helps eliminate inaccuracies that arise when users don’t (or can’t) accurately express their feelings about a product or service in a survey or interview.

Usability research can also be done effectively using Face Reading technology. Instead of inviting users into a lab and physically observing them, researchers can observe users through a webcam that transmits live images to the Face Reading app.

How is Face Reading used in practice?

In addition to market research and usability research, Face Reading is used by advertisers and retailers to measure response to their digital campaigns in real time and make adjustments along the way to maximize ROI.

Retailers, for example, also use Face Reading to determine the prevailing mood among shoppers at any given moment. They will then use this information to customize the experience, for example by playing more appropriate music or changing the types of ads or notifications they show.

The automotive industry is also using Face Reading technology in combination with other assistance features to wake up drivers if they fall asleep behind the wheel.

In the entertainment industry, Face Reading technology can be used to record and analyze audience reactions to video games, movies, and more. Entertainment companies can then use this data to produce more interesting content for their audience.


In this article after trying several techniques, the facial recognition technique works well. Face The recognition system is based on facial recognition. This the system can be used to identify an unknown person. The future work is for recognition algorithm. In the system evolved only by recognizing 30 degrees angle changes that should improve. Gait recognition can be merged with facial recognition systems. Poor lighting conditions. Our system will work fine, but it does not the perfect solution.
