Evaluation of two methods based on EMD for elimination of blink from EEG

摘要

EEG signals collected from cortex are often contaminated with the eye electrical activity, which increase the difficulty in analyzing the EEG and to obtaining clinical information. In this paper, two different methods based on Empirical Mode Decomposition, for elimination of blink in EEG is compared. The performance index of this experiment is the correlation coefficient between bands of pure EEG and filtered EEG, which indicate the method based on combination of EMD and adaptive filtering outperforms the EMD approach for elimination of blink contamination from EEG signal.
