Abstract Expression recognition is a key issue in natural human-computer interaction. The machine leaning method is most commonly used to recognize expression from face images or image sequences, and good results are acquired. However, expression recognition is considered as a special process of human vision and it may provide a new way to realize emotion recognition in computer by simulating human emotional information process. The expression recognition using extended neural networks is presented. It simulates the structure of emotion-attention circuit in human brain by adding feedback control for attention in hidden layer. The effectiveness of the proposed approach is evaluated on Cohn Kanade expression database, and good results are obtained.
