Facial Expression Detection using Machine Learning

Abstract

Now-a-days people are very much comfortable with images, anything in an image is representation of something. Also a human face is representation of a facial expression. From a human image we can find facial expression and emotion. A single person face can be detected easily in modern science. But it is difficult to find expression of emotion. Sometimes, it is hard to hard find exact facial expressions or emotions even from a still image. To solve this problem machine is the best solution. As a part of machine learning, facial expression detection is a large field of research. Our research work mainly focused on represent the facial expression or emotion of a human.If the object in a picture is a human being, it will read the facial expression of that human object and represents that expression in text like sad, happy or normal. In our work, we’ve tried to establish a system which can easily represent a facial expression from an image, if the object is human then read the facial expression. Facialexpression detection was a very challenging part of this research. The dataset used is collected from online platform. Machine Learning method is used to make our system, in this system we try to train the dataset and expect the output on facial expression detection.
