    • A fast marching method for the area based affine distance 

      Silva, Moacyr Alvim Horta Barbosa da; Teixeira, Ralph Costa; Pesco, Sinesio; Craizer, Marcos
      In a previous paper, it was proved that the area based affine distance of a convex region in the plane satisfies a non-homogeneous Monge-Ampere differential equation. Based on this equation, in this paper we propose a fast ...
    • A numerical scheme for the curvature equation near the singularities 

      Craizer, Marcos; Pesco, Sinesio; Teixeira, Ralph Costa
      In this paper we propose a modification in the usual numerical method for computing the solutions of the curvature equation in the plane . This modification takes place near the singularities of the image. We propose to ...
