A novel approach for epileptic seizure detection

A new on-line adaptive methodology is introduced for detecting a suspected epileptic seizure from an electroencephalogram (EEG). This is achieved by using the angle between two progressive oblique spaces. Two seizure indices are introduced. In the absence of seizure, the EEG remains short time stationary, and hence the seizure indices remain approximately unity. If and when abnormality or epileptic seizure activity occurs, the EEG becomes …
