Combining visual channels of facial expression and body gesture is a(1) ______ way to accomplish effective affect analysis. The psychological researchers (2) ______ studied about body language suggests that the integration of facial expression and body gesture is a mandatory process occurring early in human processing stream. So the two modalities should be processed in a joint feature space, rather than fused at the decision-level. (3) ______ of the main difficulties for the feature-level fusion is that the features from different modalities may be incompatible, and the (4) ______ between different feature spaces is unknown. Our motivation is that, as facial expression and body gesture are two sets of measurements for the affective state, conceptually they are correlated. (5) ______ ,this analysis can establish their relationship, deriving a semantic “affect” space, in which the face and body features are compatible and can be effectively fused.
