Motor Imagery Classification Using Mu and Beta Rhythms of EEG with Strong Uncorrelating Transform Based Complex Common Spatial Patterns

Figure 2

Average power spectra of all trials of 105 subjects. The power spectra show the first six IMFs, 1st IMF to the 6th IMF out of a total of 11 IMFs, which were decomposed in order using MEMD. and correspond to the mu (8–13 Hz) and beta rhythms (13–25 Hz), respectively. The high peak at 60 Hz, indicating the power noise, was not to be considered.
