A robust minimum variance beamforming approach for the removal of the eye-blink artifacts from EEGs K. Nazarpour Yodchanan Wongsawat Saeid Sanei Soontorn Oraintara Jonathon Chambers 2134/5628 https://repository.lboro.ac.uk/articles/conference_contribution/A_robust_minimum_variance_beamforming_approach_for_the_removal_of_the_eye-blink_artifacts_from_EEGs/9555599 In this paper a novel scheme for the removal of eye-blink (EB) artifacts from electroencephalogram (EEG) signals based on the robust minimum variance beamformer (RMVB) is proposed. In this method, in order to remove the artifact, the RMVB is provided with a priori information, i.e., an estimation of the steering vector corresponding to the point source EB artifact. The artifact-removed EEGs are subsequently reconstructed by deflation. The a priori knowledge, namely the vector corresponding to the spatial distribution of the EB factor, is identified using a novel space-time-frequency-time/segment (STF-TS) model of EEGs, provided by a four-way parallel factor analysis (PARAFAC) approach. The results demonstrate that the proposed algorithm effectively identifies and removes the EB artifact from raw EEG measurements. 2009-12-08 17:18:46 untagged Mechanical Engineering not elsewhere classified
