This paper p resents a novel technique developed for the identification of facial exp ressions in video sources. The method uses two step s: facial exp ression feature extraction and exp ression classification. Firstwe used an active shape model (ASM) based on a facial point tracking system to extract the geometric features of facial ex2 p ressions in videos. Then a new type of local support vectormachine (LSVM) was created to classify the facial ex2 p ressions. Four different classifiers using KNN, SVM, KNN2SVM, and LSVM were compared with the new LSVM. The results on the Cohn2Kanade database showed the effectiveness of ourmethod
