Study of Facial Micro-expressions in Psychology

Abstract

The study of micro-expressions has undergone a big change as a result of contemporary development in the areas of human–computer interaction (HCI) and affective computing. This chapter will highlight the need for the study of micro-expressions. It would focus on two major approaches to evolve parameters for the automatic detection of human facial expressions—the facial action coding system (FACS) and facial animation parameters (FAPs). Besides summarizing the major developments in the area of psychology and other areas, it would also explore the ways in which neuropsychological studies can contribute to this domain of knowledge.
