EEG Classification for Hybrid Brain-Computer Interface Using a Tensor Based Multiclass Multimodal Analysis Scheme

Figure 12

A visualization example of the assembled tensor for a hybrid of MI and SSVEP task (imagining left hand movements and focusing on the 8 Hz stimulus simultaneously). The spectrograms are shown at each channel according to channels distribution over scalp, with time ranging from 0 to 4 s and frequency ranging from 5 to 30 Hz. The spectrograms at C3, Oz, and C4 channels are enlarged in the bottom.
