Abstract : In Recent years, the research interest to automated analysis of human affective behaviour has attracted increasing attention in psychology, bio-medical, human computer interaction, linguistics, neuroscience, computer science and related disciplines. Since emotions plays an important role in the daily life of human being, the need and importance of automatic emotion recognition has grown with increasing role of human computer interaction applications. Emotion places major role of brain cognition for medically monitoring patients emotional states or stress levels, creating Animated movies, monitoring automobile drivers alertness / drowsiness levels, Human-Robot interaction, Advanced Gaming which enabling very young children to interact with computers, designing techniques for forensic identification, etc. This paper survey from the published work papers, since 2013 till date. The paper surveys about the six prototype expression in human through the various modes of extracting emotion. The paper detailed about that the face detection and tracking, features extraction mechanisms and the technique used for expression classification by the face modelling of state-of-the-art classification. The paper also discussed on multimodal expression classifier of human, i.e. from body and face. Notes also presented the tracking human through sensor and ends with the challenges and future with intention of helping students and researchers who are new to this field.
