Abstract:
This paper presents an approach to automatic
visual emotion recognition from two modalities: face and
body. Firstly, individual classifiers are trained from
individual modalities. Secondly, we fuse facial expression
and affective body gesture information first at a featurelevel,
in which the data from both modalities are combined
before classification, and later at a decision-level, in which
we integrate the outputs of the monomodal systems by the
use of suitable criteria. We then evaluate these two fusion
approaches, in terms of performance over monomodal
emotion recognition based on facial expression modality
only. In the experiments performed the emotion
classification using the two modalities achieved a better
recognition accuracy outperforming the classification
using the individual facial modality. Moreover, fusion at
the feature-level proved better recognition than fusion at
the decision-level.
