Jet Marching Methods for Solving the Eikonal Equation
WebDec 20, 2024 · We develop a family of compact high-order semi-Lagrangian label-setting methods for solving the eikonal equation. These solvers march the total 1-jet of the eikonal, and use Hermite interpolation to approximate the eikonal and parametrize characteristics locally for each semi-Lagrangian update. We describe solvers on … WebMay 16, 2000 · The Fast Marching Method is a numerical algorithm for solving the Eikonal equation on a rectangular orthogonal mesh in O(M log M) steps, where M is the total number of grid points. The scheme relies on an upwind finite difference approximation to the gradient and a resulting causality relationship that lends itself to a Dijkstra-like … WebMotion trajectory obtained with the extended fast marching scale because it guarantees a motion path (if it exists), and method. ...
