Description

This paper presents a methodology to do morphing between image represented objects, attending to their physical properties. It can be used amongst images of different objects, or otherwise, between different images of the same object. According to the used methodology the given objects are modelled by the Finite Element Method, and some nodes are matched by Modal Analysis. Then, by solving the Dynamic Equilibrium Equation the displacement field is determined, which allows the simulation of the objects’ deformation. This physical approach also allows the computation of the involved strain energy, therefore the estimated morphing can be represented by the local or global strain energy values. This paper also describes the solution used to simulate only the non-rigid components of the involved deformation.
