Abstract

Neurophysiological signals are often corrupted by noise that is significantly stronger than the signal itself. In electroencephalographic (EEG) data this may amount to figures of −25 dB (Flexer, 2000), for electromyography (EMG) or functional magnetic resonance imaging (fMRI) the situation is similar. The problem of the recovery of information under noise has been dealt with extensively in the literature of signal and image processing (Whalen, 1971; Castleman, 1996).
