| Abstract: | In the study of brain-computer interfaces,a method of feature extraction and classification used for two kinds of imaginations is proposed.It considers Euclidean distance between mean traces recorded from the channels with two kinds of imaginations as a feature,and determines imagination classes using thresh- old value.It analyzed the background of experiment and theoretical foundation referring to the data sets of BCI 2003,and compared the classification precision with the best result of the competition.Th... |
