Current Elastic SfT (Shape from Template) methods are based on l2-norm minimization. None can accurately recover the spatial location of the acting forces since l2-norm based minimization tends to find the best tradeoff among noisy data to fit an elastic model. In this work, we study shapes that ar…
This paper focusses on safe screening techniques for the LASSO problem. We derive a new sphere test, coined RFNE, exploiting the firmly non-expansiveness of projection operators. Our test generalizes some methods of the literature but, unlike the latter, exploits approximated primal-dual solutions o…
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. We propose the first fully linear least-squares SfT method modeling elastic deformations. It relies on a set of Solid Boundary Constraints SBC to p…
