Embodiment 1

[0031] figure 1 A flow chart of a group emotion recognition method provided by an embodiment of the present invention is shown, and the flow of the method includes steps S101 to S105. The specific implementation principle of each step is described in detail as follows:

[0032] Step S101, acquiring group pictures to be subjected to group emotion recognition.

[0033] Wherein, the group pictures refer to pictures including human bodies. In the embodiment of the present invention, the group picture to be subjected to group emotion recognition is specified by the user.

[0034] Step S102, perform feature extraction on the group picture, and obtain facial expression features and human body emotion features of the group picture.

[0035] Specifically, preprocessing is performed on the group photos, and feature extraction is performed from the preprocessed group photos, so as to improve the accuracy of acquired facial expression features and human emotion features.

[0036] As a...

Embodiment 2

[0142] Corresponding to the group emotion recognition method described in the above embodiment, image 3It shows a structural block diagram of a group emotion recognition device provided by an embodiment of the present invention, the device can be applied to a smart terminal, and the smart terminal can include a user equipment that communicates with one or more core networks via a radio access network RAN, the The user equipment can be a mobile phone (or "cellular" phone), a computer with a mobile device, etc. For example, the user equipment can also be a portable, pocket, hand-held, computer built-in, or vehicle-mounted mobile device that communicates with wireless The access network exchanges voice and / or data. For another example, the mobile device may include a smart phone, a tablet computer, a personal digital assistant PDA, a sales terminal POS, or a vehicle-mounted computer. For ease of description, only parts related to the embodiments of the present invention are sho...

Embodiment 3

[0192] Figure 4 It is a schematic diagram of a smart device provided by an embodiment of the present invention. Such as Figure 4As shown, the smart device 4 of this embodiment includes: a processor 40, a memory 41, and a computer program 42 stored in the memory 41 and operable on the processor 40, such as a group emotion recognition program. When the processor 40 executes the computer program 42, it realizes the steps in the above-mentioned embodiments of the various group emotion recognition methods, for example figure 1 Steps 101 to 105 are shown. Alternatively, when the processor 40 executes the computer program 42, it realizes the functions of the modules / units in the above-mentioned device embodiments, for example image 3 Function of units 31 to 35 shown.

[0193] Exemplarily, the computer program 42 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 41 and executed by the processor 40 to complete this inventi...

Abstract

The invention is applicable to the technical field of information processing, and provides a group emotion identification method, a device, an intelligent device and a storage medium. Extracting features of the group pictures to obtain facial expression features and human emotion features of the group pictures; According to the facial expression feature and the trained first neural network model,obtaining the facial expression feature probability in the group pictures; Obtaining the probability of human emotion features in the group pictures according to the human emotion features and the trained second neural network model; The facial expression feature probability and the human emotion feature probability are fused, and the group emotion of the group photograph is determined based on the fused result. The method can stably recognize the group emotion of group photos and improve the accuracy of group emotion recognition.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a group emotion recognition method, device, intelligent device and storage medium. Background technique [0002] With the development of social networks and self-media such as WeChat and Youtube in recent years, thousands of social pictures are uploaded to the public Internet or private space every day, such as party photos, wedding photos, etc. Therefore, the automatic analysis of group emotions by computers has a wide range of applications, such as emotional recognition of tourist groups in scenic spots, emotional recognition of audience groups in competitions or concerts, and emotional state recognition of customers in restaurants. It can also be used to predict group behavior, such as pro-social behavior, employee absenteeism, group violence prediction, etc. The group emotion recognition algorithm is designed to automatically recognize group emotio...
