Facial Expression Recognition Based on Image Feature

Abstract

Facial expressions provide an important behavioral measure for the study of emotions, cognitive processes and social interaction and thus automatic facial expression recognition systems can provide a less intrusive method to apprehend the emotion activity of a person of interest. With the availability of low cost imaging and computational devices, automatic facial recognition systems now have a potential to be useful in several day-to-day application environments like in identifying suspicious persons in airports, railway stations and other places with higher threat of terrorism attacks.
