WebThe focus of this chapter is to establish the equivalence between a Monge-Amp`ere equation and an HJB equation, and to propose a finite difference method for the equivalent HJB formulation that converges in the viscosity sense. This chapter serves as a foundation for solving the more complicated image registration problems. WebThen, the HJB equation (5) has a unique viscosity solution, which corresponds to the Q-function. Theorem 3 The Q-function (3) is the unique viscosity solution of the HJB equation (5). Moreover, it is a bounded and Lipschitz continuous function. Proof To accommodate the Lipschitz continuity constraint on controls, we consider an augmented
