Automatic Recognition of Human Facial Expression by Computer Image Processing

Abstract

This paper gives a method of analyzing human facial expressions by measuring the shape of the eye, brow and mouth, and of identifying emotional expressions. Facial expressions play a very important role in communication in our dailylife. Without any verbalized words we can often get considerable information about the emotional states of a person from their face. In order to analyze facial expressions, computer graphics of the human face is developed. In this experiment 4 parameters are selected. The automatic recognition of expressions is done by processing a digital image of a human face which is obtained by a video camera. Our final goal is to develope a method of identifying facial expressions which can be applied to Man-Machine interface.
