On the Exact Recovery Conditions of 3D Human Motion from 2D Landmark Motion with Sparse Articulated Motion
We prove that for the relaxed formulation we are able to recover the exact 3D human motion from 2D landmarks if and only if the PKSP property is verified.
Elastic Shape-From-Template With Spatially Sparse Deforming Forces
We prove that filling this property is necessary and sufficient for the relaxed formulation to: (i) retrieve the ground-truth 3D deformed shape, (ii) recover the right spatial domain of non-zero deforming forces.
A Linear Least-Squares Solution to Elastic Shape-From-Template
We cast SfT (Shape-from-Template) as the search of a vector field (X, dX), composed of the pose X and the displacement dX that produces the deformation.
Monocular Template-Based 3D Reconstruction of Extensible Surfaces with Local Linear Elasticity
We extend the method of isometric surface reconstruction and more recent work on conformal surface reconstruction.
