Figure 4. — Results of EOG artifact removal on the real EEG data. (a) The raw EEG recordings with eye movement and blink artifacts, as well as the simultaneous recordings of the EOG signals; (b) Components separated by SSA; (c) Components separated by SOBI; (d) Components separated by ICA; (e) IMFs decomposed by applying EMD on the last two components in (b); (f) The raw EEG recording and the corrected EEG signals by each methods on channel Fp1; (g) The zoomed artifacts-corrected signals in the artifact-free epoch on channel Fp1.
