TLDR
In this paper, a method and apparatus for volumetric image analysis and processing is described, which is able to obtain geometrical information from multi-dimensional (3D or more) images.Abstract:Â
A method and apparatus for volumetric image analysis and processing is described. Using the method and apparatus, it is possible to obtain geometrical information from multi-dimensional (3D or more) images. As long as an object can be reconstructed as a 3D object, regardless of the source of the images, the method and apparatus can be used to segment the target (in 3D) from the rest of the structure and to obtain the target's geometric information, such as volume and curvature.read more

A Variational Level Set Approach to Multiphase Motion
TL;DR: In this paper, a coupled level set method for the motion of multiple junctions (of, e.g., solid, liquid, and grain boundaries), which follows the gradient flow for an energy functional consisting of surface tension and bulk energies, is developed.

Regular Article: A PDE-Based Fast Local Level Set Method
TL;DR: A fast method to localize thelevel set method of Osher and Sethian and address two important issues that are intrinsic to the level set method, which reduces the computational effort by one order of magnitude, works in as much generality as the original one, and is conceptually simple and easy to implement.

Fast Sweeping Algorithms for a Class of Hamilton--Jacobi Equations
TL;DR: A Godunov-type numerical flux is derived for the class of strictly convex, homogeneous Hamiltonians that includes H(p,q) and it is shown that convergence after a few iterations, even in rather difficult cases, is indicated.
