Figure 3. — Results of EOG artifact removal on an example EEG data set from the 20 artificially contaminated ones. (a) The artificially contaminated EEG data with eye movement and blink artifacts (shown in the first six EEG channels) and the corresponding EOG signals used in the mixing procedure (shown in the last two channels); (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 mixed, the pre-contaminated EEG and the corrected EEG signals by each methods on channel Fp1; (g) The power spectrum estimates for the pre-contaminated EEG and the corrected EEG signals by each methods on channel Fp1; (h) The zoomed artifacts-corrected signals in the artifact-free epoch.
