Subtle expression recognition based intelligent evaluation system and method

Abstract

The invention discloses a subtle expression recognition based intelligent evaluation system and a method. The subtle expression recognition based intelligent evaluation system comprises a facial imageacquisition module, a feature extraction module, a user interaction module, an evaluating question bank and a grading module. The system is capable of providing a reliable evaluation data by catchingand analyzing subtle expression of a tested person while answering different evaluation questions, evaluating emotions of the tested person in the case of different questions and correcting an evaluation result according to the emotion state of the tested person during the test process. The evaluation scope of the next question can be judged according to the acquired emotion state of the tested person during the answering process, and the evaluation questions can be adjusted through the evaluating question bank, so as to supply a specific evaluation content.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an intelligent evaluation system and method based on micro-expression recognition. Background technique [0002] Micro-expression is a term in psychology. People express their inner feelings to each other by making some expressions. Between different expressions or within a certain expression, the face will "leak" other information. A micro-expression is a quick expression that lasts only 1 / 25 of a second or 1 / 5 of a second, expressing the true emotions that people try to suppress and hide. [0003] Facial recognition uses a camera as an identification information acquisition device to obtain the facial image of the identification object in a non-contact manner, and the computer system compares it with the database image to complete the identification process. [0004] Due to the lack of analysis of the external behavior of the test personnel, the traditional ev...

AI Technical Summary

Problems solved by technology

[0004] Due to the lack of analysis of the external behavior of the test personnel, the traditional evaluation method based on the interface operation cannot accurately grasp the state of the test subjects and make timely and effective adjustments. When the test personnel avoid the test problems, will adversely affect the reliability of the evaluation results

At the same time, the evaluation system that provides fixed or random evaluation test questions is difficult to guarantee the accuracy of the evaluation results for different testees
