Removal of EOG Artifacts from EEG Recordings Using Stationary Subspace Analysis

Figure 3

Results of EOG artifact removal on an example EEG data set from the 20 artificially contaminated ones. The artificially contaminated EEG data with eye movement and blink artifacts are shown in the first six EEG channels of (a) and the corresponding EOG signals used in the mixing procedure are presented in the last two channels of (a). Components separated by SSA, SOBI, and ICA are shown in (b), (c), and (d), respectively. The zoomed mixed, precontaminated EEG, and corrected EEG signals by each method on channel Fp1, C3, and O1 are depicted in (e), (f), and (g), respectively.
