Detection and localization of epileptic seizures using ICA
Saeid Sanei, Mohamed Amin Latif, L. Shaker · 2005
An effective and simple algorithm for localization of epileptiform sources of the EEG signals within the brain has been developed here. The method includes a constrained blind source separation (CBSS) algorithm, which attempts to separate and localize the epileptifom EEG sources. The significance of the new developed algorithm is the incorporation of a proper constraint into the joint approximate diagonalization formulation. The fixed locations of the electrodes together with the normalized correlations between the estimated sources and the observed EEGs provide a sufficient geometrical information to localize the sources.
