Figure 3

Distributions of BP features. This figure shows distributions of BP features extracted from different time-frequency regions for two classes (circle represents left hand, asterisk represents right hand). (A) Distribution of BP features extracted from the time-frequency region with the largest TFDF. (B) Distribution of BP features extracted from a time-frequency region (8 to 30 Hz, 0.5 to 2.5 s after cue on-set) in the μ band. (C) Distribution of BP features extracted from the time-frequency region with the largest F score. (D) Distribution of BP features extracted from the time-frequency region with the largest Euclidean distance. The line shows the best linear separation boundary in each case.
