WebNov 1, 2013 · For this, we use the FMM algorithm [15], [16], [17] to compute the distance map to a boundary ∂Ω. FMM is a numerical scheme for computing solution to the Eikonal equation of the form: (6) ∇ T = 1 in Ω, with T = 0 on ∂ Ω. The solution T of (6) is the distance map of the Ω voxels to the boundary ∂Ω. FMM explicitly maintains a ... The 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 time at which the contour crosses a point is obtained by solving the equation. … simple scrapbooking ideas
