Curvelet and fast marching method‐based technique for efficient artifact detection and removal in dermoscopic images

International journal of imaging systems and technology (Print), 2021
Effective detection and removal of the artifacts from dermoscopic images require the analysis of structures within lesions for accurate cancer detection. But the dermoscopic images acquired may be affected by image acquisition noise, variation in texture,

PyKonal: A Python Package for Solving the Eikonal Equation in Spherical and Cartesian Coordinates Using the Fast Marching Method

Seismological Research Letters, 2020
This article introduces PyKonal: a new open-source Python package for computing travel times and tracing ray paths in 2D or 3D heterogeneous media using the fast marching method for solving the eikonal equation in spherical and Cartesian coordinates ...

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, 2008
Fast 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 ...

Fast Marching Methods

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 \(\Omega\).
