Paper Abstract

Motivated from problems in computer vision, in this paper we introduce a new class of problems in system theory, which we call, perspective problems in system theory. The word perspective is derived from vision problems wherein feature points on an object are assumed to be projected perspectively on a screen during the process of imaging. Consequently, the basic problem of perspective system theory that we consider in this paper is to observe the initial condition or to identify the parameters of a dynamical system with the aid of a perspective observation function. Based on this concept, we present a new approach for solving the problem from point and line correspondence.
