  abstract =	 " Functional models are frequently used in computer
                  vision and photogrammetry,as they enable the
                  mathematical formulation of several problems such as
                  pose computation and more generally the parameter
                  estimation problem.However,the structural properties
                  of such models have only seldom been studied.This
                  contribution is dedicated to the analysis of such
                  properties.We propose a new formalism that enables
                  the analysis and design of functional models. ",
