Embodiment Construction

[0043] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] EEG is to obtain the signal of brain activity by recording the electrical activity of the cortex, but the electrical activity of the brain is a very weak bioelectrical signal, which requires complex signal amplification and analog-to-digital conversion technology to be recorded outside the skull into the brain signal of neuronal activity.

[0045] In addition, due to the complex signal environment around EEG acquisition, EEG signals are susceptible to noise interference. Among them, the most common sources of noise that affect the quality of EEG signals include myoelectric activity, power frequency interference, and white noise. Specifically, the existing EEG noise methods have at least the following problems:

Abstract

The invention discloses a method and device for removing the artifacts of electroencephalogram signals and electronic equipment. The method comprises the steps of: collecting electroencephalogram signals, and carrying out preprocessing on the electroencephalogram signals; detecting artifacts generated by myoelectricity activity in the preprocessed electroencephalogram signals; removing the artifacts in the electroencephalogram signals, so as to obtain an electroencephalogram signal data set; and inputting the electroencephalogram signal data set into a pre-trained adversarial self-encoding model, so as to enable the adversarial self-encoding model to perform noise quality evaluation and denoising processing on the electroencephalogram signals. By means of the technical schemes, the noise component in the electroencephalogram signals can be removed, so that real brain activity electric signals can be extracted.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method, device and electronic equipment for removing artifacts of electroencephalogram signals. Background technique [0002] Electroencephalography (Electroencephalography, EEG) is a graph obtained by amplifying and recording the spontaneous biopotential of the brain from the scalp through sophisticated electronic instruments. It is the spontaneous and rhythmic electrical activity of brain cell groups recorded by electrodes. Activity. [0003] In the process of realizing the present invention, the inventors found the following problems in the prior art: due to the complex signal environment around the EEG acquisition, the EEG signal is easily mixed with noise, which may interfere with the EEG signal. Contents of the invention [0004] The invention provides a method, device and electronic equipment for removing artifacts of electroencephalogram signal...
