Abstract： It is of great value to recognize concealed emotions for early warning of public security issues. Micro-expression is a vital channel to reveal concealed emotions. However, there are relatively few studies on concealed emotions, and micro-expressions are challenging to recognize because of their subtle magnitude and short duration. Existing Laboratory studies of micro-expression have few practical applications. Therefore, the perception and expression of concealed emotion should be systematically investigated by collecting micro-expression samples in an ecological situation, while synchronically collecting EEG signals for better labeling of micro-expressions. We spot and recognize concealed emotions mainly through micro-expressions, accompanied by face color analysis, gaze estimation, and contactless physiological signals measurement. Then, we verify and modify our system and method in two realistic public security related application scenarios: a Recognition Assistant System for the aggressive and suicidal behaviors of psychiatric patients and a Concealed Emotion Detection System for prisoners interview.
