Problem Definition
Reconstruction of 3D structure of deforming objects objects from a video sequence taken from a moving camera.

Key Contributions
Demonstration that temporal regularity is sufficient to reconstruct structure. Object-independent basis over trajectories which do not have to be estimated anew for each sequence. Duality of trajectory basis and shape basis representations used in earlier literature.
Shape Basis
as used in earlier literature

Trajectory Basis
for the same dataset

Comparison with Ground Truth Mocap Data Our Method
