WebThe Fast Marching Method (FMM), in its simplest form, can be used to compute the arrival times at grid cells for a monotonously expanding interface. One application of this method is to set the speed of the interface to one which enables computation of distance fields, where the closest distance to the interface is assigned to every cell in a grid. Web2.1. Multistencils Fast Marching Method The two key points in this algorithm are the selection of the neighborhood and the T i,j computation. Several meth-ods were proposed to improve the FMM. In this section we are going to explain one of the most accurate, the Mul-tistencils Fast Marching Method (MSFM) [13]. Whereas
