Automatical recognition of facial expression is an interesting and challenging problem,which has so many applications such as expression synthesis,human-robot interaction,metal state identification,intelligent tutoring systems,operator fatigue,music for mood,and clinical *** vital step of a successful approach is deriving features from raw facial *** existed methods of features extraction are the hand-crafted features based on geometric features or appearance features,and the auto-learned *** utilize the benefit of low computation of hand-crafted features and the high-representation of auto-learned features,we firstly proposed the combined features CNN-CBP with putting together centralized binary patterns(CBP) features and Convolutional Neural Network(CNN) *** then,we classified the features using Support Vector Machine(SVM).With the help of the CNN-CBP features,we achieved average recognition accuracy of 97.6%on the Extended Cohn-Kanade datasets and 88.7%on the Japanese Femal Facial Expression datasets based on 10-cross validation.
