The automatic detection and classification of EEG epileptic wave have great clinical significance. This paper proposes an empirical mode decomposition (EMD) and support vector machine (SVM) based classification method for non-stationary EEG. Firstly, EMD was used to decompose EEG into multiple empirical mode components. Secondly, effective features were extracted from the scales. Finally, the EEG was classified with SVM. The experiment indicated that this method could achieve good classification result with accuracy of 99 % for interictal and ictal EEGs.
脑电图癫痫波的自动检测与分类具有重要的临床意义。本文提出了一种基于经验模态分解(EMD)和支持向量机(SVM)的非平稳脑电图分类方法。首先,利用EMD将脑电图分解为多个经验模态分量。其次,从这些分量中提取有效特征。最后,用SVM对脑电图进行分类。实验表明,该方法能取得良好的分类结果,对发作间期和发作期脑电图的分类准确率可达99%。
