Dynamic hand gesture recognition based on 3D pattern assembled trajectories
Résumé
Over the past few years, advances in commercial 3D sensors have substantially promoted the research of dynamic hand gesture recognition. On a other side, whole body gestures recognition has also attracted increasing attention since the emergence of Kinect like sensors. One may notice that both research topics deal with human-made motions and are likely to face similar challenges. In this paper, our aim is thus to evaluate the applicability of an action recognition feature-set to model dynamic hand gestures using skeleton data. Furthermore, existing datasets are often composed of pre-segmented gestures that are performed with a single hand only. We collected therefore a more challenging dataset, which contains unsegmented streams of 13 hand gesture classes, performed with either a single hand or two hands. Our approach is first evaluated on an existing dataset, namely DHG dataset, and then using our collected dataset. Better results compared to previous approaches are reported.
