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 ...

Fast marching tree: A fast marching sampling-based method for optimal motion planning in many dimensions [PDF]
The International Journal of Robotics Research, 2015 In this paper we present a novel probabilistic sampling-based motion planning algorithm called the Fast Marching Tree algorithm (FMT*). The algorithm is specifically aimed at solving complex motion planning problems in high-dimensional configuration spaces.

Fast Marching Methods - parallel implementation and analysis
, 2008 Fast Marching represents a very efficient technique for solving front propagation problems, which can be formulated as partial differential equations with Dirichlet boundary conditions, called Eikonal equation: $F(x)|\nabla T(x)|=1$, for $x \in \Omega ...

Fast and accurate surface normal integration on non-rectangular domains
Computational Visual Media, 2017 The integration of surface normals for the purpose of computing the shape of a surface in 3D space is a classic problem in computer vision. However, even nowadays it is still a challenging task to devise a method that is flexible enough to work on non ...

The Information Geometry of Sensor Configuration
Sensors, 2021 In problems of parameter estimation from sensor data, the Fisher information provides a measure of the performance of the sensor; effectively, in an infinitesimal sense, how much information about the parameters can be obtained from the measurements ...
