InactiveCN107260166ASuper GaussianLarge kurtosisDiagnostic recording/measuringSensorsLinear driftTime domain
The invention relates to a practical method for removing artifacts from online electroencephalograph, and belongs to the technical field of biomedical information processing. The method corrects a down sampling of the reduced channel real-time electroencephalograph signals, a power frequency notch wave and a linear drift, the discrete wavelet transform is used for decomposing the down sampling of the reduced channel electroencephalograph signals into 7 layers, and single channel electroencephalograph signals are converted to multiple channels. The wavelet coefficients are reconstructed and used as inputs to ICA. Fast acquisition of independent components is implemented using Fast ICA algorithm. According to the characteristics of time domain, frequency domain and ordinal correlation of each artifact in the independent component, which is different from the normal electroencephalograph component, hierarchical clustering algorithm is introduced to cluster each independent component, the categories of artifacts are automatically recognized, the artifacts are reconstructed after the zero artifact is zero, and the reconstructed electroencephalograph signals are obtained. The method solves the problem that the prior method cannot automatically identify and remove a variety of conventional electroencephalograph artifacts in the absence of reduced channel.
