AI Technical Summary

Problems solved by technology

Due to the large number of attribute categories and complex rules of facial expressions, in the existing facial expression recognition methods, each recognition model needs to memorize more content, which leads to complex calculations in the recognition process of human facial expressions. The recognition accuracy and recognition efficiency are relatively low

Embodiment Construction

[0025] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as figure 1 As shown, the embodiment of the present invention provides a computer facial emotion recognition system, including

[0027] Man-machine operation module, used to input various control commands and data call commands;

[0028] The face image acquisition module is used to obtain the real-time face image of the person to be identified;

[0029] The living body recognition module is used to judge whether the image source is alive or not based on the optical flow method through the near-infrared detection module; If the source is a living body, start the image processing module for image processing;

[0030] The image proc...

Abstract

The invention discloses a computer face emotion recognition system, which comprises a face image acquisition module, a living body recognition module, an image processing module, a facial features position positioning module, an image feature extraction module, a three-dimensional face reconstruction module, and a face recognition module. The present invention acquires the face image to be recognized and facial features depth image data based on the kinect depth sensor, and recognizes the emotional data in the facial image through the shape and position of the facial features, thereby realizing the recognition of the emotion in the facial image.

Description

technical field [0001] The invention relates to a face recognition system, in particular to a computer face emotion recognition system. Background technique [0002] The basic facial expression categories are divided into 8 categories, namely anger (anger), contempt (contempt), disgust (disgust), fear (fear), happiness (happy), neutral (neutral), sadness (sadness) and surprise ). Facial expression recognition is a technology that studies how to make a computer obtain and distinguish facial expressions from static images or video sequences. If a computer can accurately understand human facial expressions and recognize which category a human facial expression belongs to, it will greatly change the relationship between humans and computers, thereby achieving better human-computer interaction effects. [0003] The current facial expression recognition methods are mainly based on random forest algorithm, expression feature dimensionality reduction method, or expression classifi...
