  Extending the Liouville-Caputo definition of a fractional derivative to a
nonlocal covariant generalization of arbitrary bound operators acting on
multidimensional Riemannian spaces an appropriate approach for the 3D shape
recovery of aperture afflicted 2D slide sequences is proposed. We demonstrate,
that the step from a local to a nonlocal algorithm yields an order of magnitude
in accuracy and by using the specific fractional approach an additional factor
2 in accuracy of the derived results.
