摘要: A multigrid anisotropic diffusion algorithm for image processing is presented. The implementation provides an efficient hierarchical relaxation method that facilitates the application of to time-critical processes. Through a V-cycle, equations are successively transferred coarser grids and used in coarse-to-fine error correction scheme. When coarse grid with trivial solution reached, estimates residual can be propagated original refine solution. main benefits approach rapid intraregion smoothing reduction artifacts due elimination low-frequency error. theory developed. Then, intergrid transfer functions, techniques, coefficients, boundary conditions discussed. analysis includes examination storage requirements, computational cost, quality. Finally, experimental results reported demonstrate effectiveness approach.
