Hybrid rigid and non-rigid image-based modeling of articulated figures

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.
