Behaviors, actions, poses, facial expressions and speech; these are considered as channels that convey human emotions.Extensive research has being carried out to explore the relationships between these channels and emotions.This paper proposes a prototype system which automatically recognizes the emotion represented on a face.Thus a neural network based solution combined with image processing is used in classifying the universal emotions: Happiness, Sadness, Anger, Disgust, Surprise and Fear.Colored frontal face images are given as input to the prototype system.After the face is detected, image processing based feature point extraction method is used to extract a set of selected feature points.Finally, a set of values obtained after processing those extracted feature points are given as input to the neural network to recognize the emotion contained.
