SIAM Review, 1999
The author considers numerical methods for solving the nonlinear eikonal equation \[ |\nabla u(x)|= F(x)\quad\text{in }\Omega\subset \mathbb{R}^2\quad\text{or }\mathbb{R}^3,\tag{1} \] under given boundary conditions \(u=g\) on some prescribed curve or surface \(\Gamma\) in \(\Omega\).

An Image Inpainting Technique Based on the Fast Marching Method [PDF]
Journal of Graphics Tools, 2004 Digital inpainting provides a means for reconstruction of small damaged portions of an image. Although the inpainting basics are straightforward, most inpainting techniques published in the literature are complex to understand and implement. We present here a new algorithm for digital inpainting based on the fast marching method for level set ...

Optimal control using the Fast Marching Method
2009 35th Annual Conference of IEEE Industrial Electronics, 2009This paper presents the applications of the Fast Marching and the Buffered Fast Marching Methods to solve typical control problems. Calculus of Variations and Optimal Control problems can be solved using the Euler-Lagrange or the Pontryagin equations and solving analytically or numerically the corresponding differential equations systems.

On the implementation of fast marching methods for 3D lattices [PDF]
, 2001 This technical report discusses Sethian's Fast Marching Method and its higher accuracy variant. Both methods may be used to compute the arrival times at the points of a discrete lattice of a front which is monotonously expanding. Applications of the method include arrival time computation and the construction of distance fields for 2D or 3D objects ...

IEEE Transactions on Medical Imaging, 2002 A method is presented for determining paths of anatomical connection between regions of the brain using magnetic resonance diffusion tensor information. Level set theory, applied using fast marching methods, is used to generate three-dimensional time of ...

Distributed fast marching methods
Proceedings of the 15th ACM Mardi Gras conference: From lightweight mash-ups to lambda grids: Understanding the spectrum of distributed computing requirements, applications, tools, infrastructures, interoperability, and the incremental adoption of key capabilities, 2008Fast Marching represents a very efficient technique for solving the front propagation problems which can be formulated as boundary value partial differential equations |∇T(x, y)| = 1/F(x, y) on Ω, with Dirichlet boundary condition T(x, y) = 0 on ∂Ω. We show that the problem of computing the distance map across a smooth sampling domain can be posed in ...

Robust skeletonization using the fast marching method
IEEE International Conference on Image Processing 2005, 2005We have recently developed a level set based-framework for computing medial curves or curve skeletons CS for arbitrary 2D shapes as well as tubular and articulated 3D objects. The proposed framework is robust, fully automatic, computationally efficient, and produces curve skeletons that are connected, centered, thin, and less sensitive to boundary ...

A Generalized Fast Marching Method on Unstructured Triangular Meshes
SIAM Journal on Numerical Analysis, 2013In this paper we extend the generalized fast marching method (GFMM) presented in [E. Carlini et al., SIAM J. Numer. Anal., 46 (2008), pp. 2920--2952] to unstructured meshes. The GFMM generalizes the classical fast marching method, in the sense that it can be applied to propagate interfaces with time-dependent and changing sign velocity.
