Figure 8: The results of CP detection on the assembled EEG samples with different value of sample size and test position CPK. For with different from 27 to 210, (a1–a4) the assembled EEG samples with the assigned test position CPK, (b1–b4) the e-CP, (c1–c4) the error of e-CP, (d1–d4) the accuracy of e-CP, and (e1–e4) the computation time. In the -axis of (b–e), the methods “1,” “2,” “3,” and “4” stand for BSTKS, KS, , and SSA, respectively.
