Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] The micro-expression recognition method provided by this application can be applied in such as figure 1 In the application environment of , the client (computer device) communicates with the server through the network. The client collects video or image data, and sends the video or image data to the server, and the server performs processing after obtaining the video or image data, and outputs the recognition result of micro-expressions. Among ...

Abstract

The invention discloses a micro-expression recognition method and device, a computer device and a storage medium, and the method comprises the steps: firstly, judging whether a face image of a testedperson exists in an acquired current image to be recognized or not; if the face image of the tested person exists in the current image to be recognized, performing micro expression recognition on thecurrent image to be recognized based on a micro expression recognition model, and outputting an emotion recognition result of the current image to be recognized; if the face image of the tested persondoes not exist in the current image to be recognized, updating a dynamic threshold value; and obtaining the next image to be identified according to the updated dynamic threshold, taking the next image to be identified as the current image to be identified, and returning to execute the step of judging whether the face image of the tested person exists in the current image to be identified. And the calculation amount of the server side can be reduced while the processing precision is ensured, and the overall processing efficiency is improved.

Description

technical field [0001] The present invention relates to the field of AI, in particular to a micro-expression recognition method, device, computer equipment and storage medium. Background technique [0002] Microexpressions are very fleeting, involuntary facial expressions that humans reveal when they try to suppress or hide their true emotions. The difference between it and ordinary expressions is that the duration of micro-expressions is very short, only 1 / 25 second to 1 / 5 second. Therefore, most people are often unaware of its existence. When talking with others, because the micro-expressions are short-lived and difficult to recognize, only a low-speed camera (30 frames per second) is used to record the facial expressions of the test subjects for a short time. The video that needs to be analyzed in the study is as high as 300,000 frames. In this case, because the number of micro-expressions captured is too small, only descriptive statistics can be performed on the expres...
