In this paper, the differences between two motor imagery tasks are captured through microstate parameters (occurrence, duration and coverage, and mean spatial correlation (Mspatcorr)) derived from a novel method based on electroencephalogram microstate and Teager energy operator. The results show that the significance between microstate parameters for two tasks is different ( < 0.05) with paired -test. Furthermore, these microstate parameters are utilized as features. Support vector machine is utilized to classify the two tasks with a mean accuracy of 93.93%, which yielded superior performance compared to the other methods.
本文通过基于脑电微状态和 Teager 能量算子的新方法得出的微状态参数(出现率、持续时间和覆盖率以及平均空间相关性(Mspatcorr))捕捉到两种运动想象任务之间的差异。结果表明,配对检验表明两种任务的微状态参数之间存在显著差异(<0.05)。此外,这些微状态参数可用作特征。支持向量机用于对两种任务进行分类,平均准确率为 93.93%,与其他方法相比表现更优。
