Motor Imagery Classification Using Mu and Beta Rhythms of EEG with Strong Uncorrelating Transform Based Complex Common Spatial Patterns

Figure 6

Spatial patterns of the top three subjects in descending order, who had the best classification rates: subject 34 (96.13%), 72 (95.51%), and 7 (94.89%). The left two topographies show the spatial patterns for the covariance matrices () of the left and right-hand tasks, respectively, while the right two topographies show the spatial patterns for the pseudocovariance matrices (). Note that the patterns of and are prominently different, meaning can produce additional information to .
