Abstract: The human face can exhibit complex and strong changes that are both unpredictable and varying in time. Nowadays, facial expression recognition has become a emerging and research topic due to advancement in this field. In this paper, we study about many facial expression techniques, but these two techniques are most utilized for facial expression recognition. In existing method atlases are constructed using conventional group-wise registration method due to which lot of subtle and important information lost. To overcome this limitation sparse based atlas construction method and Spatio-temporal information are represented for better performance in recognition process. This paper presents a quick survey of facial expression recognition
