基于TQWT的癫痫脑电信号的识别
Identification of Epileptic EEG Signals based on the Tunable Q-factor Wavelet Transform
摘要
Abstract
For the problem of identifying and classifying epileptic EEG signals , we proposed an effective technique based on the tunable Q-factor wavelet transform ( TQWT) .Firstly, the TQWT was employed to decompose EEG signal into several wavelet subba-nds.Then, according to the frequency band of epileptic abnormal waves , the EEG signal was reconstructed adaptively via correspond-ing TQWT wavelet subbands .The root mean square value and peak -to-peak value indicators were calculated as feature vector .Fi-nally, the support vector machine (SVM) was introduced for classification.Moreover, the proposed method was applied to analyze real EEG data collected from the Epilepsy Research Center , University of Bonn, Germany.The results demonstrate that the proposed tech-nique can effectively detect epilepsy disease from EEG signals with good classification accuracy of 98%.关键词
