A method and device for identifying and reminding abnormal micro-expressions

Abstract

The invention relates to an abnormal micro-expression recognition and reminding method and device. The device used by the method comprises a wearable terminal apparatus, a cloud signal processing unit, and a processing result reverse sending unit, wherein the wearable terminal apparatus is worn on the body of a tester and used for capturing and transmitting micro-expression data of a tested person; the cloud signal processing unit is used for computing the micro-expression data of the tested person; the processing result reverse sending unit is used for sending back an abnormal micro-expression result required for reminding in an instruction given by the cloud signal processing unit to the wearable terminal apparatus through a wireless network; the cloud signal processing unit is used for processing the micro-expression data of the tested person in three stages through wireless signal receiving: the first stage of computing micro-expression baseline data of the tested person; the second stage of capturing the micro-expression data in a test problem Q&A stage; and the third stage of comparing the micro-expression data at the second stage with the baseline data at the first stage, and performing relative operation, filtering to obtain the abnormal micro-expression result.

Description

technical field [0001] The invention relates to a method and device for identifying and reminding abnormal micro-expressions, belonging to the field of intelligent expression recognition. Background technique [0002] A micro-expression is a very rapid expression that lasts only 1 / 25 to 1 / 5 second, expressing the real emotions that people try to suppress and hide. Microexpressions are very fleeting, involuntary facial expressions that humans reveal when they try to suppress or hide their true emotions. As an effective clue to identify lies, micro-expressions can be applied in security, judicial, clinical and other fields. [0003] Existing wearable (portable) expression recognition devices are divided into two categories, one is wearable or portable equipment, which is worn on the tester, and the other uses a fixed camera to take pictures of the tester, which is not portable but has the same function as the first Classes are similar. [0004] The first type is the equipme...

[0005] The second category is a non-wearable device with a fixed camera (lens). The disadvantage of this type of device is that the device itself has more restrictions on the tested person, and it is easy to interfere with the natural expression of the tested person.
