Emotional Analysis using Deep Learning

Abstract

Emotions are mental states that accompany physiological changes in the face, resulting in facial expressions. Sympathy, anger, worry, joy, fright, and other significant emotions are a few examples. Facial expressions play a significant role in non-verbal communication because they encapsulate a person's emotions. There has been a great deal of research done on computer modelling of human emotions. Computer modelling of human emotions has been made possible by computer technology. However, it is still in its infancy. The authors attempted to overcome limitations and create new opportunities as well as gain a better understanding and implement this simple form of human interaction in proposed computer-aided world. It has been made possible to evaluate and interpret genuine facial expressions in real time thanks to new techniques for collecting facial expressions and quick, highresolution pictures. The FER (Facial Expression Recognition) method currently relies on motionless frames, which makes it very hard to recognize foreground from background in the absence of motion information. This study describes a real-time facial expression identification system that detects faces using HAAR cascading classification and classifies facial expressions using convolutional neural networks. The system utilizes a webcam to dynamically display emotion text and accurately categorizes seven major emotions, including anger, disgust, fear, happiness, sadness, surprise, and neutrality. Real-time facial expression recognition may be utilised in a number of real-world applications, including as airport security, trade, and medical monitoring.
