Abstract :
A multiresolution method to match deformed contours is presented. Our approach has been inspired by the method due to Duncan et al. (1990) and Cohen et al. (1992). The innovation of our work is in the incorporation of a new smoothness term in the elastic fitting criterion. As a result the computational complexity is reduced and the equation corresponding to the minimization of the fitting criterion has a simple interpretation. We investigate the necessary and sufficient conditions for the minimization of the fitting criterion using variational calculus
