Facial expression plays significant role for human beings to communicate their emotions.Automatic facial expression analysis is a flourishing area of research in computer science, and it is also still a challenge.This paper discusses the application of a natural network based facial expression recognition using fisherface.Back propagation neural network is used as a classifier for classifying the expressions.For face portion segmentation and localization, integral projection method is used.The accuracy of system performance have evaluated on a public database "Japanese Female Facial Expression (JAFFE)".The experimental results show the effectiveness of our scheme.The best average recognition rate achieves 89.20%.
