From: Impact of Affective Multimedia Content on the Electroencephalogram and Facial Expressions

The same three Audio-visual Cues as with the EEG (Texture-based Homogeneity, Texture-based Contrast, and Pitch-based Harmonic Flux) were found to be most correlated with Facial Expressions. We plot above the five best associated Facial Expressions Cues and denote weights of their associated CCA coefficients.
