Embodiment Construction

[0034] Such as figure 1 As shown, in one embodiment of the present invention, the facial motion detection model creation method based on EEG comprises the following steps:

[0035] 1) Acquisition of EEG signals and pre-exclusion of data, using EEG detection equipment to collect EEG data when blinking, clenching teeth, and opening eyes upwards. EEG detection equipment is used to detect brain waves, digitally store and store brain waves Displayed equipment, such as electroencephalographs, EEG detection equipment, the time-domain amplitude of the EEG signal collected by the EEG detection equipment is between -400uv and 400uv, and the data whose time-domain amplitude is between -400uv and 400uv is more than 55% of the extracted data The segment is regarded as a valid data segment, and the rest of the data is directly discarded without subsequent processing;

[0036] 2) Segmentation of the EEG signal to be identified, analyze the short-term energy and zero-crossing rate of the eff...

Abstract

A method for detect facial movement in real time based on EEG signal, which can obtain a, solves that problem of recognition and classification of three kinds of facial movement, detects facial movement in real time, has high detection accuracy, and can provide more control instructions for EEG detection equipment.

Description

technical field [0001] The invention belongs to the technical field of detection and analysis, in particular to a method for real-time detection of facial movements based on brain electricity. Background technique [0002] The study of the human brain has always been the focus of people's attention. There are about 10 billion neurons in the human brain. In order to study human brain activity, functional magnetic resonance imaging (fMRI) is often used in medicine to study human physiological health. , For example: Observing changes in the cerebral cortex related to learning and memory, differences in the cerebral cortex between epilepsy patients and normal people, Alzheimer's disease, stroke, multiple sclerosis and Parkinson's syndrome and other brain diseases Treatment. [0003] With the development of science and technology, brain waves, as a new way of measuring brain activity, have gradually entered people's field of vision. Brain wave is a fast and dynamic time series,...
