Abstract :
In this paper, a novel facial expression analysis system is proposed, which directly recognizes warp image of face. And the warp image can be obtained by the automatic AAM processing. The system consists of mainly four modules, warp processing, Gabor filtering, Adaboost training processing, SVM training and testing processing. We also compared the performance of our method to the system trained on the output of face detector (geometry normalization images). And the method using warp preprocessing can reach a high level of accuracy above 90%
