Enhanced Performance by Time-Frequency-Phase Feature for EEG-Based BCI Systems
Figure 3
The topography of four different mu feature types of a subject session. The mean feature value during period is used for the plot. (a) The topography of power. (b) The topography of the instantaneous amplitude (IA). (c) The topography of the instantaneous phase (IP). (d) The topography of the instantaneous frequency (IF).
