Deformable models, i.e., active contours and active
meshes, are useful tools in image processing and computer
vision, because of their ability to take the shape of real 2D/3D
objects. The original formulation of the models is defined on the
spatial domain and it is based on the minimization of an energy
functional through the Euler-Lagrange differential equations.
In this paper, a new formulation is proposed in the frequency
domain, for the adaptation process of the contours and meshes to
the external forces. The presented frequency approach provides
an easier and more computationally efficient implementation,
allowing the use of deformable models to a greater number of
areas.Este trabajo está financiado por el Ministerio de Ciencia y
