Research On Eye Micro-expression Recognition Based On Deep Learning

Since our society has entered the information age,various emerging technologies have sprung up.New technologies have made our lives more convenient and comfortable.Face recognition is one of them,which has given us a simple,efficient and popular application in bio cryptography.With the development of face recognition technology,people have further analyzed and identified facial expressions.Changes in facial expressions are one of the most basic ways for humans to express emotions.In many cases,people can read each other's inner emotions through the other's facial expressions.Even when people deliberately suppress their expressions,they will inadvertently reveal subtle and short expression changes.Humans have retained this instinct after centuries of evolution.In contrast to simple,macro expressions like crying and laughing,those complex,micro expressions that are inadvertently revealed are agreed to become micro expressions.The study of micro-expressions dates back to 1966.Haggard et al.Believed that micro-expressions were inseparable from the self-defense mechanism of the human subconscious,but their findings did not attract the attention of the academic community.In 1969,Ekman et al.Also found the existence and value of micro-expressions in a video of a depression patient who wanted to suppress their suicidal thoughts.When looking at this video roughly,Ekman et al.Did not find anything unusual until they After observing and analyzing the video frame by frame,it was found that the facial expression change of the depression patient was 1/12 of a second,which they called a micro facial expression.The research on facial micro-expressions has gradually increased in recent years,but the research on the micro-expressions of the eyes has been scarce.When people deliberately cover their faces,such as wearing a mask or covering their mouths,the success rate of facial micro-expression recognition will be greatly reduced,and even faces cannot be recognized.Human eye micro-expressions have extremely important functions in many aspects,such as criminal investigations in the field of security,fatigue driving supervision,prediction of suspect behavior,political negotiations in the field of political psychology,and students'mental health in the field of education,etc.Value cannot be ignored.
