Sub-Riemannian Fast Marching in SE(2) [PDF]
, 2015 We propose a Fast Marching based implementation for computing sub-Riemanninan (SR) geodesics in the roto-translation group SE(2), with a metric depending on a cost induced by the image data. The key ingredient is a Riemannian approximation of the SR-metric.

Comparison Principle for a Generalized Fast Marching Method [PDF]
SIAM Journal on Numerical Analysis, 2009 In \cite{CFFM06}, the authors have proposed a generalization of the classical Fast Marching Method of Sethian for the eikonal equation in the case where the normal velocity depends on space and time and can change sign. The goal of this paper is to propose a modified version of the Generalized Fast Marching Method proposed in \cite{CFFM06} for which we

Wildfire Spreading Simulator Using Fast Marching Algorithm [PDF]
SNE Simulation Notes Europe, 2021 Programs that can predict wildfire behavior are a very useful tool in terms of extinguishing these fires more effectively. State of the art wildfire simulators present some drawbacks such as not being sufficiently user-friendly, being expensive, requiring great computational power or having poor graphical representation. This paper presents a prototype

A comparison of fast marching, fast sweeping and fast iterative methods for the solution of the eikonal equation [PDF]
Telfor Journal, 2013 We compare the computational performance of the Fast Marching Method, the Fast Sweeping Method and the Fast Iterative Method to determine a numerical solution to the eikonal equation. We point out how the Fast Iterative Method outperforms the other two thanks to its parallel processing capabilities.

Application of Fibonacci heap to fast marching method
Open Physics, 2021 The fast marching method (FMM) is an efficient, stable and adaptable travel time calculation method. In the realization of this method, it is necessary to select the minimum travel time node from the narrow band many times.

Fast marching based superpixels
Mathematical Morphology - Theory and Applications, 2020 AbstractIn this article, we present a fast-marching based algorithm for generating superpixel (FMS) partitions of images. The idea behind the algorithm is to draw an analogy between waves propagating in a heterogeneous medium and regions growing on an image at a rate depending on the local color and texture.
