Abstract
Seizures in epileptic patients affect tremendously their daily life in terms of accidents during driving a vehicle, swimming, using stairs, etc. Automatic seizure detectors are used to detect seizure as early as possible so that an alarm can be given to patient or their family for using anti-epileptic drugs (AEDs). In this paper, an algorithm has been proposed for automatic seizure onset detection by analysis of electroencephalogram (EEG) signals. The method is based on few wavelet transform-based features and two statistical features without wavelet decomposition for improving the performance of detector. The mean, energy, and entropy were calculated on different wavelet decomposed subbands, and mean absolute deviation and interquartile range were calculated on raw signal. Classification between seizure and nonseizure types of EEG signals was done successfully by linear classifier. The algorithm was applied to CHB-MIT EEG dataset for seizure onset detection and achieved 100 % sensitivity with mean latency of 1.9 s.
