Problems solved by technology

However, the emotional expression of behavioral gestures is different due to the influence of age, gender and culture, and the recognition rate of emotional recognition based solely on behavioral gestures is low.
At present, there are no published research results on emotional cognition based solely on behavioral postures in a natural state.

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0039] Such as figure 1 As shown, a human natural state emotion recognition method based on the combination of expression and behavior dual modes includes the following steps:

[0040] S1: Establish the emotional cognition framework of the two-level classification model, in which: the first-level classification model is the rough classification of emotional cognition, and the rough classification of emotional cognition is divided into: excitement, depression, and uncertainty; the second-level classification model For the sub-classification of emotional cognition, the sub-category of ...

Abstract

The invention relates to a human natural state emotion identification method based on double-mode combination of expression and behavior. The human natural state emotion identification method comprises the following steps of S1, establishing an emotion cognition architecture in two classification modes; S2, performing human body area detection on a natural-gesture human body image of video input; S3, performing characteristic point extraction on the image in a human body trunk subarea, obtaining a characteristic point motion track according to the characteristic points in image frames at different time, acquiring a main motion track which reflects human body behavior from the characteristic point motion track by means of a clustering method, extracting a human body trunk motion characteristic from the main motion track; S4, acquiring an emotion cognition coarse classification result according to the human body trunk motion characteristic; S5, performing face expression characteristic extraction on the image of the face sub-area; and S6, outputting an emotion cognition fine-classification result which corresponds with the searched face expression characteristic. Compared with the prior art, the human natural state emotion identification method has advantages of high identification precision, wide application range, easy realization, etc.

Description

technical field [0001] The invention relates to an emotion recognition method, in particular to a human natural state emotion recognition method based on the combination of expression and behavior. Background technique [0002] Rich emotional expression is an effective way for human beings to understand each other, and it is one of the characteristics that distinguish human beings from other creatures. With the development of computer technology, the use of machines to realize automatic recognition of human emotions in various scenes will more and more affect human daily life, and it is also one of the key topics in the field of artificial intelligence research. It has a very wide range of applications in psychology, clinical medicine, intelligent human-computer interaction, social security, distance education, business information statistics and other fields. The intelligent perception of human emotions can be achieved through various channels such as images, language, tex...
