Abstract

This paper investigates the performance of calibration techniques on synthetic Electroencephalography (EEG) data. Brain source localization was performed using an iterative algorithm. A transfer-function-based calibration technique was developed. This technique can be applied in two forms: external calibration and autocalibration. For a low density EEG array system, it was shown that the proposed calibration technique can offer improved performance relative to previously published work.
