Abstract: Emotion recognition is the task of machines trying to analyze, interpret and classify human emotion through the analysis of facial features. AI emotion recognition is a very active current field of computer vision research that involves facial emotion detection and the automatic assessment of sentiment from visual data. Human-machine interaction is an important area of research where artificially intelligent systems with visual perception aim to gain an understanding of human interaction. AI emotion recognition leverages machine learning, deep learning, computer vision, and other technologies to recognize emotions based on object and motion detection. This paper presents the role of AI in emotion recognition. In this case, the machine treats the human face as an object. Through computer vision, the machine can observe facial features like the mouth, eyes, and eyebrows, notice their position, and track their movements over time. It then compares the captured data from the movements with already learned emotions.
