Dynamic Principal Component Analysis with Nonoverlapping Moving Window and Its Applications to Epileptic EEG Classification

Figure 6

Three-dimensional features scatter plot obtained from the DPCA method for the test signals in Sets A, B, C, D and E for the FFPC method and for PCPEM method in both epilepsy diagnosis (using signals from Sets A, B, C and D) and seizure detection (using signals from Sets C, D and E). The scatter plots in green, red, yellow, blue and black colors stands for signals in Sets A, B, C and D and E, respectively.
