A Self-Calibration Method of Zooming Camera
In this article we proposed a novel approach to self- calibrate a camera with variable focal length. We show that the estimation of camera’s intrinsic parameters is possible from only two points of an unknown planar scene. ...
Pseudo Focal Points Along Lorentzian Geodesics and Morse Index
(ADVANCED NONLINEAR STUDIES, INC, 2010)
Given a Lorentzian manifold (M,g), a geodesic gamma in M and a timelike Jacobi field Y along gamma, we introduce a special class of instants along gamma that we call Y-pseudo conjugate (or focal relatively to some initial ...
