Journal ArticleDOI
Reflection in a Level Set Framework for Geometric Optics
TL;DR: In this article, an alternative approach based on the foundation presented in [Osher, Cheng, Kang, Shim, and Tsai (2002)] is introduced, which allows the level set method to be considered for realistic applications involving reflecting surfaces in geometric optics.
Journal ArticleDOI
An Eulerian Approach for Vortex Motion Using a Level Set Regularization Procedure
TL;DR: In this article, an Eulerian, fixed grid approach is presented to solve the motion of an incompressible fluid, in two and three dimensions, in which the vorticity is concentrated on a lower dimensional set.
Journal ArticleDOI
A Finite Element Method for a Boundary Value Problem of Mixed Type
Arthur G. Deacon,Stanley Osher +1 more
TL;DR: In this article, a boundary value problem for the Lavrent'ev-Bitsadze differential equation of mixed type is divided into an elliptic problem involving an unusual boundary condition on the parabolic line, and a hyperbolic problem.
Proceedings ArticleDOI
MRI resolution enhancement using total variation regularization
Shantanu H. Joshi,Antonio Marquina,Stanley Osher,Ivo D. Dinov,John D. Van Horn,Arthur W. Toga +5 more
TL;DR: The edge enhanced reconstruction is shown to yield significant improvement in resolution, especially preserving important edges containing anatomical information, as well as a pre-processing step to improve skull-stripping segmentation of brain images.
Using geometry and iterated refinement for inverse problems (1): total variation based image restoration
TL;DR: In this paper, a new iterative regularization procedure for inverse problems based on the use of Bregman distances was introduced, with particular focus on problems arising in image processing.
