EEG-Based BCI System Using Adaptive Features Extraction and Classification Procedures

Figure 7

Three examples of maps in subject-specific frequency bins. We chose to display 3 participants who exhibited very different levels of BCI control: P03, P06, and P10. The figure shows how maps resulting from “correctly classified + above threshold” signals (a) for each participant present approximately the same shape but higher values than the case of “correctly classified” signals without threshold (b). To allow for comparability, the corresponding maps in (a)/(b) share the same colourmap bounds.
