摘要 提出了基于信号频带能量和相同步作为脑电特征向量,实现对左右手运动意识任务的分类方法.用线性判别式算法对左右手运动想象脑电模式进行识别,识别正确率最高达到了86.43%,与只用特定频带能量作为脑电特征分类结果相比,效果更好.为大脑运动意识任务的分类提供了新思路. A method for single trial on-line classification of imaginary hand movements, based on band power and phase synchronization derived from EEG, is proposed. The event-related EEG patterns during left and right hand motor imagery are identified by using the linear discriminant algorithm. The results show that the method is effective and the correct rate of classification is up to 86.43 %. It might provide a new way for the classification of mental tasks.
