Multigrid Methods

MultiresolutionImageProcessing1)MultigridMethods: In scientific computing, multigrid methods are a popular choice for the solution of large systems of linear equations that may stem from the discretization of Partial Differential Equations (PDEs). One of the most popular PDEs is the Poisson equation in order to model diffusion processes. It is similar to the equation to be solved in HDR compression, which is explained in detail in [10]. The V-cycle, as a simple scheme of a multigrid method, is shown in Algorithm 1.
