Abstract


The homotopy perturbation method is implemented to solve
nonlinear equations. Based on this method, a multi-step scheme is
constructed for a kind of Hamilton-Jacobi formulations by assuming
the homotopy parameter is a linear function of time. Using this
multi-step scheme, a minimal surface regularization equation is
solved, which designates a regularization process that doesn't
smooth the image with the same weight in all the spatial
directions. Some image denoisying examples illustrate its
effectiveness and convenience.
