Visual estimation of pointed targets for robot guidance via fusion of face pose and hand orientation ?
Problem formulation: given a number of possible pointed targets, compute the target that the user points to. Estimate head pose by visually tracking the off-plane rotations of the face. Recognize two different hand pointing gestures (point left and point right). Model the problem using the DempsterShafer theory of evidence. Use Demspsters rule of combination to fuse information and derive the pointed target.
