Discrimination between Ictal and Seizure-Free EEG Signals Using Empirical Mode Decomposition

الملخص EN

A new method for analysis of electroencephalogram (EEG) signals using empirical mode decomposition (EMD) and Fourier-Bessel (FB) expansion has been presented in this paper.

The EMD decomposes an EEG signal into a finite set of band-limited signals termed intrinsic mode functions (IMFs).

The mean frequency (MF) for each IMF has been computed using FB expansion.

The MF measure of the IMFs has been used as a feature in order to identify the difference between ictal and seizure-free intracranial EEG signals.

It has been shown that the MF feature of the IMFs has provided statistically significant difference between ictal and seizure-free EEG signals.

Simulation results are included to illustrate the effectiveness of the proposed method.
