Fast convergence layout algorithm for drawing graphs in marching-graph [PDF]
, 2008 Marching-Graph is a new visualization that integrates the graph metaphor and the spatial metaphor into a single visualization. It provides users with highly interactive maps for accessing the logical structures of information that has the geographical ...

Two Fast Marching Methods for Hamilton–Jacobi Equations [PDF]
PAMM, 2007 AbstractWe introduce and analyze two new Fast Marching (FM) methods based on a semi‐Lagrangian (SL) approximation (see [2] for a more complete presentation). The Characteristics driven Fast Marching method accepts more than one node at every iteration using a dynamic condition which leads to a faster convergence.

EDGE PRESERVING FILTERS USING GEODESIC DISTANCES ON WEIGHTED ORTHOGONAL DOMAINS [PDF]
, 2008 We introduce a framework for image enhancement, which smooths images while preserving edge information. Domain (spatial) and range (feature) information are combined in one single measure in a principled way.

A Modified Fast Marching Method [PDF]
, 2003 In most, if not all fast marching methods published hitherto, the input cost function and the output arrival time are sampled on exactly the same grid. But since the input data samples are differences of the output samples we found it natural to separate the input and output grid half a sampling unit in all coordinates (two or three).We also employ 8 ...

Fully Isotropic Fast Marching Methods on Cartesian Grids [PDF]
, 2010 The existing Fast Marching methods which are used to solve the Eikonal equation use a locally continuous model to estimate the accumulated cost, but a discontinuous (discretized) model for the traveling cost around each grid point. Because the accumulated cost and the traveling (local) cost are treated differently, the estimate of the accumulated cost ...

Application of Snell's law in reflection raytracing using the multistage fast marching method
Earthquake Research Advances, 2021 Accurate calculations of travel times and raypaths of reflection waves are important for reflection travel time tomography. The multistage shortest path method (MSPM) and multistage fast marching method (MFMM) have been widely used in reflection wave ...

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.
