A novel method is proposed for the absolute pose estimation of a central 2D camera with respect to 3D depth data without use any dedicated calibration pattern or explicit point correspondences. The has no specific assumption about source: plain information expected from sensing device and used capture images. Both perspective omnidirectional cameras are handled within single generic model. Pose...

This paper gives a classification up to isotopy of automorphisms (self-homeomorphisms) of 3-dimensional handlebodies and compression bodies, analogous to the Nielsen-Thurston classification of automorphisms of surfaces. Indecomposable automorphisms analogous to pseudo-Anosov automorphisms are identified and called generic. The first steps are taken towards understanding generic automorphisms us...

In this paper, we consider inner automorphisms that leave invariant fixed subspaces of real and complex Clifford algebras—subspaces grades determined by the reversion grade involution. We present groups elements define such study their properties. Some these Lie can be interpreted as generalizations Clifford, Lipschitz, spin groups. corresponding algebras. results reformulated for case more gen...
