WebEEG signals are recorded from healthy and alcoholic subjects during visual object recognition task. Threshold of 100 V is used to remove the eye blink artifact and the gamma sub band (30-50 Hz) is extracted using elliptic band pass filter of 6th order. ... model and eigenvector PSD estimation methods (MUSIC) in frequency domain are used as ... WebJan 25, 2024 · However, subtracting the estimated eye-blink artifact directly from the contaminated EEG signal will also remove the low-frequency components (0.5–12 Hz) of the EEG signal. This can be a cause of concern in applications such as driver fatigue detection, where the spectral energy of low-frequency EEG components is used to …
