Problems solved by technology

[0003] At present, many emotional models have appeared in the field of emotional computing, but most of them are only suitable for emotional computing in discrete states. For the natural interaction process between humans and service robots, the continuous spatiotemporal characteristics of cognitive emotional states are still not satisfactory.

Abstract

An emotion recognition device comprises an expression cognitive module, a micro-expression cognitive module and a weighted fusion module. The expression cognitive module is used for mapping emotions to a continuous emotion space for recognition. The micro-expression cognitive module is used for recognizing a tiny emotion change. The weighted fusion module is used for determining an emotional state. The emotion recognition device can accurately recognize the emotions.

Description

technical field [0001] The invention relates to the technical field of emotion recognition, in particular to an emotion recognition device. Background technique [0002] With the rapid development of artificial intelligence science, how to enable computers to recognize human expressions and obtain human emotional states has attracted more and more attention from computer science, psychology and other disciplines. [0003] At present, many emotional models have appeared in the field of emotional computing, but most of them are only suitable for emotional computing in discrete states. For the natural interaction process between humans and service robots, the continuous spatiotemporal characteristics of cognitive emotional states are still unsatisfactory. Contents of the invention [0004] In view of the above problems, the present invention aims to provide an emotion recognition device. [0005] The purpose of the invention is achieved through the following technical soluti...
