Fig. 3: Feature extraction method.

This figure demonstrates the use of the original spectrum and FOOOF-algorithm aperiodic fit for the extraction of four beta-band power measures: the maximum power (Max); the maximum flattened (i.e. after removal of the aperiodic signal component) power (Max_flat); the area under the curve (AUC); and the flattened area under the curve (AUC_flat).
