Abstract

The recognition of continuous, natural signing is very challenging due to the multimodal nature of the visual cues (fingers, lips, facial expressions, body pose, etc.), as well as technical limitations such as spatial and temporal resolution and unreliable depth cues. On the other hand, signing gestures are designed to be robustly discernible. We therefore argue in favor of an integrative approach to sign language recognition that aims to extract sufficient aggregate information for robust sign language recognition, even if many of the individual cues are unreliable. Our strategy to implement such an integrated system currently rests on two modules, for which we will show initial results. The first module uses active appearance models for detailed face tracking, allowing the quantification of facial expressions such as mouth and eye aperture and eyebrow raise. The second module is dedicated to hand tracking using color and appearance. A third module will be concerned with tracking upper-body articulated pose, linking the face to the hands for increased overall robustness.
