| الوصف: | The continuous Lambertian shape from shading is studied using a PDE approach in terms of Hamilton-Jacobi equations. The latter will then be characterized by a maximization problem. In this paper we show the convergence of discretization and propose to use the wellknown Chambolle-Pock primal-dual algorithm to solve numerically the shape from shading problem. The saddle-point structure of the problem makes the Chambolle-Pock algorithm suitable to approximate solutions of the discretized problems. |
