Embodiment Construction

[0062] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings of the description.

[0063] Such as figure 1 A described method for calculating emotion index based on human face action unit detection includes:

[0064] A method for calculating emotion index based on human face action unit detection, comprising the following specific steps:

[0065] Step 1. Establish a data set to be trained to form a face action unit database:

[0066] The facial expression images in the database are generated by the confrontation generation network, and the facial feature points are marked. The labeling process follows the supervised descent method (Supervised Descent Method, Xuehan Xiong, Fernando De la Torre; The IEEE Conference on Computer Vision and Pattern Recognition (CVPR ), 2013, pp.532-539) completed. Mark the face location area and face action unit through the face feature point information to form a training da...

Abstract

The invention belongs to the technical field of face recognition and emotion calculation technology, and specifically relates to a method for calculating an emotion index based on human face action unit detection. The specific steps include: establishing a data set to be trained, forming a database of human face action units; Unit action intensity detection; calculation of emotional index; the invention realizes the emotional process expressed through facial expressions, can convey detailed information more accurately and objectively, and can make up for the profound information that cannot be described and conveyed by language, especially for language barriers and Situational applications that cannot normally obtain language information provide a very feasible solution.

Description

technical field [0001] The present invention relates to the technical field of face recognition and emotion computing technology, in particular to a method for calculating emotion index based on face action unit detection. Background technique [0002] Emotion is the most common phenomenon in daily life. For humans with emotional fluctuations, emotional changes can be seen everywhere. It is a reflection of an individual's inner feelings about the surrounding environment. It brings people happiness and satisfaction, but also dissatisfaction and disappointment. Emotional changes affect individual behaviors and decisions, and the automatic calculation of emotional index can detect people's psychological needs and changes, and guide the application in professional fields. The sentiment index calculation can be applied to criminal investigation, justice, medicine, education, security, business and other industries in which people are engaged. Emotions can interfere with or even...
