Relevant body cues for the classification of emotional body expression in daily actions

In the context of emotional body expression, previous works mainly focused on perceptual studies to identify the most important expressive cues. Only few studies gave insights on which body cues could be relevant for the classification and the characterization of emotions expressed in body movement. In this paper, we present our Random Forest based feature selection approach for the identification of relevant expressive body cues in the context of emotional body expression classification. We also discuss the ranking of relevant body cues according to each expressed emotion across a set of daily actions.
