MultiStencils Fast Marching Methods: A Highly Accurate Solution to the Eikonal Equation on Cartesian Domains

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2007
A wide range of computer vision applications require an accurate solution of a particular Hamilton-Jacobi (HJ) equation known as the Eikonal equation. In this paper, we propose an improved version of the fast marching method (FMM) that is highly accurate

Remarks on the implementation of the fast marching method

IMA Journal of Numerical Analysis, 2008
The fast marching algorithm computes an approximate solution to the eikonal equation in O(N log N) time, where the factor log N is due to the administration of a priority queue. Recently, Yatziv et al. (2006, J. Comput. Phys., 212, 393-399) have suggested using an untidy priority queue, reducing the overall complexity to O(N) at the price of a small ...

Shape from self-calibration and Fast Marching Method

2008 19th International Conference on Pattern Recognition, 2008
Shape-from-shading methods recover 3-D shape from intensity images. Often, Lambertian reflectance is assumed. The Lambertian assumption is attractive because it simplifies the analysis. Alternatively, non-Lambertian reflectance, including specularity, is accommodated in methods that measure reflectance empirically either using a separate calibration ...

Fast Marching Methods

2004
The fast marching method was introduced by Sethian [190, 191, 192] as a computationally efficient solution to eikonal equations on flat domains. A related method was presented by Tsitsiklis in [205]. The fast marching method was extended to triangulated surfaces by Kimmel and Sethian in [112].

Guided depth enhancement via a fast marching method

Image and Vision Computing, 2013
Range imaging sensors such as Kinect and time-of-flight cameras can produce aligned depth and color images in real time. However, the depth maps captured by such sensors contain numerous invalid regions and suffer from heavy noise. These defects more or less influence the use of depth information in practical applications. In order to enhance the depth

A Massive Parallel Fast Marching Method

2016
In this paper we present a novel technique based on domain decomposition which enables us to perform the fast marching method (FMM) [4] on massive parallel high performance computers (HPC) for given triangulated geometries. The FMM is a widely used numerical method and one of the fastest serial state-of-the-art techniques for computing the solution to ...

Robust Fast Marching Method Based on Anisotropic Diffusion

Third International Conference on Natural Computation (ICNC 2007), 2007
As the most powerful numerical techniques for analyzing and solving interface evolution problems, level sets display interesting elastic behaviors and level set method can handle topological changes based on partial differential equations. But there are still some difficulties it must face up to, such as poor image contrast, noise, and missing or ...

Segmentation of hand radiographs using fast marching methods

SPIE Proceedings, 2006
Rheumatoid Arthritis is one of the most common chronic diseases. Joint space width in hand radiographs is evaluated to assess joint damage in order to monitor progression of disease and response to treatment. Manual measurement of joint space width is time-consuming and highly prone to inter- and intra-observer variation.
