Paper abstract
Time-frequency based methods have been shown to outperform other methods in dealing with newborn EEG. This is due to the fact that newborn EEG is nonstationary and multicomponent. This paper presents a new time-frequency based EEG seizure detection method. It uses the distribution of the interspike intervals of a high frequency slice of the time-frequency representation of an EEG epoch to discriminate between seizure and non-seizure activities. The seizure detected through this method is then tracked throughout all the available EEG channels by cross-correlating the binary encoded signals of both the detected seizure and the subsequent EEG epochs in all channels. This approach allows the study of the migrating behavior of seizure using EEG signals.}
