Fast Marching Techniques for Teaming UAV’s Applications in Complex Terrain

open access: yesDrones, 2023
In this paper, we present a study on coverage missions carried out by UAV formations in 3D environments. These missions are designed to be applied in tracking and search and rescue missions, especially in the case of accidents.

Robust semi-automated path extraction for visualising stenosis of the coronary arteries [PDF]

open access: yes, 2008
Computed tomography angiography (CTA) is useful for diagnosing and planning treatment of heart disease. However, contrast agent in surrounding structures (such as the aorta and left ventricle) makes 3-D visualisation of the coronary arteries difficult ...

Teleseismic Tomography for Imaging the Upper Mantle Beneath Northeast China

open access: yesApplied Sciences, 2020
Tomographic imaging technology is a geophysical inversion method. According to the ray scanning, this method carries on the inversion calculation to the obtained information, and reconstructs the image of the parameter distribution rule of elastic wave ...

Manitest: Are classifiers really invariant? [PDF]

open access: yes, 2015
Invariance to geometric transformations is a highly desirable property of automatic classifiers in many image recognition tasks. Nevertheless, it is unclear to which extent state-of-the-art classifiers are invariant to basic transformations such as ...

Fast marching methods for the continuous traveling salesman problem [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
We consider a problem in which we are given a domain, a cost function which depends on position at each point in the domain, and a subset of points (“cities”) in the domain. The goal is to determine the cheapest closed path that visits each city in the domain once.

Anisotropic Fast-Marching on cartesian grids using Lattice Basis Reduction [PDF]

open access: yes, 2014
We introduce a modification of the Fast Marching Algorithm, which solves the generalized eikonal equation associated to an arbitrary continuous riemannian metric, on a two or three dimensional domain.

Motion Planning Using Fast Marching Squared Method

open access: yes, 2015
Robotic motion planning have been, and still is, a very intense research field. Many problems have been already solved and even real-time, optimal motion planning algorithms have been proposed and successfully tested in real-world scenarios. However, other problems are not satisfactory solved yet and also new motion planning subproblems are appearing ...

Sub-Riemannian Fast Marching in SE(2)

open access: yes, 2015
We propose a Fast Marching based implementation for computing sub-Riemanninan (SR) geodesics in the roto-translation group SE(2), with a metric depending on a cost induced by the image data.

Nilpotent Approximations of Sub-Riemannian Distances for Fast Perceptual Grouping of Blood Vessels in 2D and 3D [PDF]

open access: yes, 2017
We propose an efficient approach for the grouping of local orientations (points on vessels) via nilpotent approximations of sub-Riemannian distances in the 2D and 3D roto-translation groups $SE(2)$ and $SE(3)$.
