Abstract

The invention discloses a multi-modal feature fusion electroencephalogram emotion recognition method based on multi-scale imaging, multi-scale and time sequence imaging algorithms are combined, electroencephalogram signals are converted into images to achieve emotion recognition, and compared with a traditional emotion recognition method based on EEG signals, space information of the electroencephalogram signals can be stored, and the recognition accuracy of the electroencephalogram signals is improved. In addition, a multi-scale algorithm can be used for reducing the calculation amount and finding a potential electroencephalogram signal mode, meanwhile, high-dimensional information is coded into the image, the image is made to contain rich information, the advantages of machine vision are fully utilized, a 2DCNN model is used for extracting high-dimensional features of the image, and a better sentiment classification result is obtained through different multi-mode feature fusion methods.

Description

technical field [0001] The invention relates to the field of physiological signal processing, in particular to a multi-modal feature fusion EEG emotion recognition method based on multi-scale imaging. Background technique [0002] Emotion is a complex psychological and physiological state, which affects people's cognition, behavior and interpersonal communication. According to cognitive and neurophysiological theories, emotions, which play an important role in human brain activity, can be detected in the brain's electroencephalogram (EEG) signals. Therefore, effective emotion recognition can be performed using EEG signals. [0003] The traditional emotion recognition method based on EEG signal mainly uses 1DCNN (Chinese interpretation: one-dimensional convolution) technology to extract the signal features of EEG, and train a classifier to realize emotion recognition. This traditional emotion recognition method only focuses on the time domain or frequency domain information...
