Smile detection : A simple Approach

Abstract

Facial expressions analysis is applicable in various vision systems, new interfaces for television and other entertainment systems, diagnosis and monitoring of deceases, speech processing, modern smart digital cameras and perceptual man-machine interfaces etc. Smile is human’s expression for happiness. Detection of smile by a machine is helpful to establish human machine interaction in many situations. Many researchers worked on facial expression recognition, but there is not much research about smile detection. In this paper we proposed a simple image-based approach to identify the smile.
