The recognition and analysis of micro-expressions based on algorithmic model is the common research content of computer and psychology, it is of theoretical and practical significance to accurately identify and analyze micro expressions. This paper introduces the definition, characteristics and recognition of micro-expression, and describes several algorithms commonly used for micro-expression recognition, to help people understand the status of automatic recognition of micro-expression. In future research, more algorithms or feature analysis methods can be used to further improve the accuracy of automatic micro-expression recognition and promote the further development of this field.
