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

Figure 9

Asymmetries of the power difference and sum of symmetric channel EEG of motor imagery tasks. (a) Asymmetry of the power difference between mu and beta rhythms from the symmetric channels. (b) Asymmetry of the power sum of mu and beta rhythms from the symmetric channels. Note that the asymmetry of the power difference shows more prominent difference between the left- and right-hand motor imagery tasks with the different signs of values, compared to the asymmetry of the power sum.
