Study and Detection of Eye Blink Artifacts in EEG Signals

Abstract

Electroencephalography is the recording of electrical activity along the scalp of a human brain. It is most often used for clinical purposes and for brain-computer interface. The Electroencephalogram signals which record the neural activity are contaminated with Eye Blink artifacts a lot which leads to problems in brain Computer Interface systems and also in clinical diagnosis. To analyze these signals it is necessary that the EEG recording should be artifact free. In this paper, we study about the eye blink artifacts which make the electroencephalogram noisy and then we detect the presence of these eye blink artifacts and localize and visualize them using Spectrogram and Continuous Wavelet Transform.
