Here is a demonstration of artifact filtering. The aim of this filtering is to cancel signals which do not originate from the brain, while keeping as best as possible those of cerebral origin (See presentation of EEG signal and artifacts).
This filtering has been performed with the AFOP method, protected by the patent PCT/FR2009/051340. A part of this method is described on : Signal processing 2007 and ICBBE 2008
