FAST AND ACCURATE EMD-CCA BASED METHOD TO REMOVE EYE BLINK ARTIFACTS FROM EEG

Electroencephalography (EEG) is non-invasive neuroimaging technique which is
used to record the electrical potentials generated by human brain activity. The EEG is
recorded through the electrodes placed on human scalp using 10-20 electrode
placement system. It is very difficult to interpret the EEG recording when it is
contaminated by noise originating from physiological activities such as; cardiac
activity, muscle activity, eye blink and an eye movement activity; which are known as
artifacts. But the most prominent artifact is the eye blink artifact, having amplitude of
10-100 times greater than the amplitude of cerebral activity which makes EEG data to
have low signal-to-noise ratio (SNR). An increased amount of activity in eye blinks
may severely impact the interpretation of the EEG. Several techniques have been
proposed by the different authors to remove eye blink artifacts from the EEG.
