Fast Methods for Eikonal Equations: An Experimental Survey [PDF]
IEEE Access, 2019 Fast methods are very popular algorithms to compute time-of-arrival maps (distance maps measured in time units) solving the Eikonal equation. Since fast marching was proposed in 1995, it has been applied to many different applications, such as robotics ...

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

Procedia Computer Science, 2016 AbstractSolving the eikonal equation allows to compute a monotone front propagation of anisotropic nature and is thus a widely applied technique in different areas of science and engineering. Various methods are available out of which only a subset is suitable for shared-memory parallelization, which is the key focus of this analysis. We evaluate three

Redundancy in All Pairs Fast Marching Method [PDF]
2006 International Conference on Image Processing, 2006 In this paper, we analyze the redundancy in calculating all pairs of geodesic distances on a rectangular grid. Fast marching method is an efficient way to estimate the geodesic distances from a point. But when calculated for all the points on the grid, this introduces certain redundancy.

Interactive Image Inpainting of Large-Scale Missing Region
IEEE Access, 2021 Image inpainting is a challenging reconstruction of the damaged image in photography, especially for more valued artwork than before. The damages are mostly caused by scratches and worn out, so they cannot be easily fixed physically.
