Multistencil fast marching method
WebThe fast marching method is a numerical method created by James Sethian for solving boundary value problems of the Eikonal equation: = / () =Typically, such a problem describes the evolution of a closed surface as a function of time with speed in the normal direction at a point on the propagating surface. The speed function is specified, and the … Web12 nov. 2024 · The fast marching method is widely employed in several fields of image processing. Some years ago a multi-stencil version (MSFM) was introduced to improve its accuracy by solving the equation for a set of stencils and choosing the best solution at each considered node.
