Abstract: Abstract: In this paper, Hilbert-Huang transform (HHT) is applied
to transfer time-domain waves of the four EEG
electrode channels (F7, F8, T3, T4) to obtain a scalp
map which is potentially useful for capturing transient
events such as epilepsy. Using Empirical Mode
Decomposition (EMD), the HHT decomposes the brain
wave into a sum of Intrinsic Mode Functions (IMFs),
and then Hilbert Spectrum of each IMF is calculated by
using Hilbert Transform. The scalp map spectrum is
sketched with energy-frequency-time distribution of
each IMF. Because the energy of spike wave and sharp
wave are contained in the scalp map spectrum, the
difference between normal and abnormal patients can be
observed through the scalp map. Experimental results
based on medical source data indicate its clinical
potentiality is extremely high.
