A Novel Fatigue Driving State Recognition and Warning Method Based on EEG and EOG Signals

Table 4

EEG and EOG characteristics.

Signal	Feature extraction method	Feature
EEG	Short-time Fourier transform	Power spectral density linear dynamic system smoothing characteristics (PSD).
		Smoothing characteristics of differential entropy linear dynamic system (DE).
EOG	Wavelet transform peak detection method	Electroocular features extracted based on independent component analysis (features_table_ica). Eye electrical features extracted based on subtraction rules (features_table_minus). Electrooculogram features extracted by fusion of subtraction rules and principal component analysis (features_table_icav_minh).
