Tóm tắt: Facial expression recognition is especially important in interaction between human and intelligent robots. Since the introduction of AAM model, there has been great change in detection accuracy. The main concern of this material is on facial expression recognition. In this paper, the recognition task is based on two methods, one of them is AAM combined with neural network, which gives better accuracy but lower speed, while the other is AAM combined with point correlation which is especially fast. Thus, it can be integrated to mobile robot platforms.
