Study on removal of eye movement and blink artifacts from EEG using PCA and JADE

We adopted methods via synchronously acquiring ECG and the elector/skin impedance,applied adaptive filter technique to remove motion artifact,obtained ECG with steady baseline.

Body movement during measurement can generate motion artifacts in photoplethysmography(PPG).

The comparison between the Extended Infomax ICA and SVD methods in efficiency in extracting blink artifacts in the electroencephalograph(EEG) signals indicates that ICA algorithms are more insensitive to disturbance even in the conditions of low signal-noise-ratio than the commonly used SVD method.

In this paper,by comparing the efficiencies of two ICA algorithms-Infomax ICA and Extended Infomax ICA methods in extracting blink artifacts and power noise in the EEG signals,it was shown that ICA algorithms were insensitive to disturbance in the conditions of low signal noise ratio,and ICA algorithms demonstrated a strong robustness in processing non stationary signals.

Blink artifacts and power noise are constantly found in EEC signals whose estimation and analysis can be strongly influenced by them.

Method of eliminating the fracture artifact of twin CCD detector CT;

Objectives:To increase accurate rate,positive rate of AEEG in diagnosis of epilepsy and distinguish accurately artifact of EEG so as to prevent misdiagnosis and missed diagnosis.

The current methods to remove artifacts from ERP and the existent problems were summarized, while the fundamental of ICA and its two key facts were introduced.
