Figure 3From: Seizure classification in EEG signals utilizing Hilbert-Huang transform Components of a seizure EEG signal. Decomposition of a seizure EEG signal by EMD. The first time series is the EEG signal. The decomposition yields 10 IMF and a residual. The IMF are the time-frequency constituents or components of the EEG signal. Frequency content is ordered in a descending order. (IMF1 has the highest frequency content).Back to article page
