Figure 6

Performance of the four different algorithms on real EEG data (8s) recorded in an epileptic patient during the interictal period: (a) One example of a typical noise-free interictal spike culminating at FT10. (b) A first 8s-epoch of data contaminated with muscle activity and the corresponding EEGs reconstructed after CCA, CoM2, 2T-EMD, and DWT. (c) A second 8s-epoch of data contaminated with muscle activity and the corresponding EEGs reconstructed after CCA, CoM2, 2T-EMD, and DWT. The results of source localization using 4-ExSo-MUSIC are represented at the bottom of each epoch of clean, noisy or denoised EEG.
