Process of generating RGB images. (1) EEG time series values from multiple locations are acquired; (2) EEG time series is divided into three subbands: theta, alpha and beta; (3) features are extracted for the three prominent frequency bands; (4) topographical maps are formed for each feature, and the sequences of topographical maps are combined to form a sequence of 3-channel images.
