Emotion Detection from Image Using Machine Learning

Abstract

Human emotions are determined by one’s action, behavior, voice tone, facial expression and body language. These are considered to be the channels to understand human emotion. Using modern technology, depth analysis has been allotted to enquire into the relationship between these emotions and the channels to understand human emotion. Human feeling recognition plays a vital role inside the social relationship. Automatic emotion recognition has been a vigorous analysis subject for quite a long period. Therefore, there unit some particular advances created throughout this range. Human emotion expresses from voice speech, voice tone, hand movement, through facial expressions and gestures of the body. Therefore, pulling out and classifying and fathoming of feeling options a great importance to the reciprocal action between the communication of human and machine. Our study intends to develop a system that mechanically identifies the feeling depicted on human face. Therefore, image process is employed to classify the universal emotions. These are happiness, sadness, anger, disgust, surprise, feared and neutral. The system takes human images of frontal face as its input. Feature purpose extraction methodology which is based on image process in this case, is employed to fetch a set of chosen feature characteristics, after the face is detected. And ultimately, when those fetched information points are given as input to the neural network in order to acknowledge the feeling ached, a set of values is generated as its output.
