The Micro-expressions Application Technology In The Application Of Duty Crime Investigation

Micro-expressions include microexpressions, micro motion and micro semantics, it is the moment people under effective stimulus, involuntary exhibit is not controlled by the thinking of instantaneous real reaction. Is based on the research on micro reaction, expression, on the basis of Darwin published in 1872, the famous "people and animals look", opened the prelude of research for human facial expression system. Darwin argued that there are six basic human emotional expression, including surprise, disgust, anger, fear, sadness, joy, and the basic principles of these expressions in detail in this paper, the fundamental. Today’s scholars study of micro reaction, including emotional expression, facial expressions, body movements, and the semantic research basic important reference in Darwin’s theory, the research laid the foundation for micro reaction.Micro reaction research and modern science and technology, neuroscience, psychology and other related scientific development is inseparable, with the continuous development of modern science and technology strength, especially the development of computer technology and high-definition high-speed video technology, to capture the fleeting moment micro-reactor, plays an extremely important role and also promote the development of micro reaction research. Reaction with micro study related technology research includes: the facial expressions and micro expression facial recognition technology research, response to body motion capture and gait analysis and research, the automatic recognition of speech response analysis and related technology. The related technology is introduced into the research of micro reaction and micro reaction application technology research has important theoretical and practical significance.Micro reaction of theoretical research, after all, is to serve for the practical work, so the micro application technology embodies the micro reaction produced the research of social values. Micro reaction technology can not only in everyday life and everyday interpersonal used for people, but also in clinical medicine, national security, play an important role in the fields of judicial investigation. Especially in the field of duty crime investigation, micro reaction application technology of easy operation, high accuracy, micro reaction application technology based on effective stimulus to the criminal suspect under micro reaction of comprehensive analysis, survey of position detection practice, ask and interrogation and lie detection, targeted investigation, make effective questioning strategies play an important role, can greatly improve the work efficiency.The author attempts through this paper, the micro reaction and micro reaction application technique system is introduced, combined with the characteristics of duty crime investigation in China, research on micro reaction application technology in the feasibility and necessity of duty crime investigation, combined with A, B district people’s procuratorate of duty crime investigation case example analysis, the response to the micro application technology in the role of duty crime investigation practice, popularization value and application specification, discusses the matters needing attention and promote complete, hope micro-reactor application technology can better play A role in the duty crime investigation.
