A Novel Fixed Low-Rank Constrained EEG Spatial Filter Estimation with Application to Movie-Induced Emotion Recognition

Figure 10

Topographies of six significant spatial filters obtained by -mean clustering of all spatial filters estimated for all subjects by using rank 6 constraint. The color is mapped from −0.5 (blue) to +0.5 (red). (a) Positive versus neutral and (b) negative versus neutral.
