Facial Expression Detection using Viola-Jones Algorithm

Abstract

An important topic in the field of Computer Vision and Artificial Intelligence is facial expression recognition. There are two medium of communication one is verbal and another is non-verbal. Among verbal and non-verbal means of communication, facial expression is a non-verbal means of communication. Facial expression plays a vital role which helps human to express their emotions, express their feelings, mental health, perspective etc. Understanding becomes easier when human and computer interact with one another if computer can response to non-verbal communication of human which is nothing but emotions expressed. In this paper, an algorithm is presented for object detection based on Viola-Jones Algorithm. This algorithm is widely used in object detection and the main property of this algorithm is that it's training is slow but detection is fast.
