Abstract:

We describe a new method for rendering new poses of articulatd figures. The long-term goal of this work is to take images or video of a person in different poses, and then render images of that person in new poses. The human body is modeled as a rigid kinematic chain. A morphing technique models non-rigid changes in shape and texture of each kinematic link. This system achieves much more generality than either pure rigid or pure non-rigid models could achieve alone.

We demonstrate results on planar motion of a single arm. From only two images of the arm, the algorithm can generate a wide range of believable poses. We believe that the new approach is powerful enough to model 3D motion of a complex, articulated figure.
