A new ghost cell/level set method for moving boundary problems:application to tumor growth [PDF]
, 2008 In this paper, we present a ghost cell/level set method for the evolution of interfaces whose normal velocity depend upon the solutions of linear and nonlinear quasi-steady reaction-diffusion equations with curvature-dependent boundary conditions.

Multiphase Image Segmentation Method Based on One Level Set Function [PDF]
Jisuanji gongcheng, 2018 When using multiple feature functions to mark different regions for image segmentation,it is necessary to find extreme values for multiple functions,resulting in the increase in computation.Aiming at this problem,a method of multi-level set marking by ...

Some numerical aspects of the level set method
Mathematical Modelling and Analysis, 1998 Many practical applications imply the solution of free boundary value problems. If the free boundary is complex and can change its topology, it will be hard to solve such problems numerically.

Deep level-set method for Stefan problems
Journal of Computational Physics, 2023 We propose a level-set approach to characterize the region occupied by the solid in Stefan problems with and without surface tension, based on their recent probabilistic reformulation. The level-set function is parameterized by a feed-forward neural network, whose parameters are trained using the probabilistic formulation of the Stefan growth condition.

Level set methods for dynamic tomography [PDF]
2004 2nd IEEE International Symposium on Biomedical Imaging: Macro to Nano (IEEE Cat No. 04EX821), 2005 In this paper, we propose a novel variational framework for the reconstruction of dynamic objects from sparse and noisy tomographic data. Using an object-based scene model, we developed a general object dynamic model based on a one to one and differentiable mapping. We then propose a novel distance between curves to incorporate the object dynamics into

A Novel Adaptive Level Set Segmentation Method [PDF]
Computational and Mathematical Methods in Medicine, 2014 The adaptive distance preserving level set (ADPLS) method is fast and not dependent on the initial contour for the segmentation of images with intensity inhomogeneity, but it often leads to segmentation with compromised accuracy. And the local binary fitting model (LBF) method can achieve segmentation with higher accuracy but with low speed and ...

COUPLING BOUNDARY ELEMENT METHOD WITH LEVEL SET METHOD TO SOLVE INVERSE PROBLEM
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2017 The boundary element method and the level set method can be used in order to solve the inverse problem for electric field. In this approach the adjoint equation arises in each iteration step.
