Abstract
Due to occlusions, the estimation of the full pose of a
human hand interacting with an object is much more chal-
lenging than pose recovery of a hand observed in isolation.
In this work we formulate an optimization problem whose
solution is the 26-DOF hand pose together with the pose
and model parameters of the manipulated object. Optimiza-
tion seeks for the joint hand-object model that (a) best ex-
plains the incompleteness of observations resulting from oc-
clusions due to hand-object interaction and (b) is physically
plausible in the sense that the hand does not share the same
physical space with the object. The proposed method is the
first that solves efficiently the continuous, full-DOF, joint
hand-object tracking problem based solely on markerless
