Scenario iii: seizure with varying localisation. (a) Localisation error of the dipole fitted on the reconstructed EEG based on a single CPD component and the two dipoles fitted on the reconstructed EEG based on BTD for various SNR values. (b) Localisation error of the dipoles fitted on the reconstructed EEG based on the sum of the first two CPD components and based on BTD for various SNR values. (c) The positions of the simulated sources (circles); the ictal source extracted by CPD (star) based on a single CPD component and by BTD (squares) for SNR = 1.
