| Abstract: | A novel method of EEG signals compression representation and epileptiform spikes recognition based on wavelet neural network and its algorithm is presented in this paper. Wavelet network not only can compress data effectively but also can recover original signal. In addition the characters of the spikes and the spike -slow rhythm are auto- detected from the time -frequency isoline of EEG signal. This method is sure to be used widely in the field of the electrophysiological signal processing and time - frequency analyzing. |
