Journal ArticleDOI
Compressed plane waves yield a compactly supported multiresolution basis for the Laplace operator
TL;DR: This paper describes an regularized variational framework for developing a spatially localized basis that spans the eigenspace of a differential operator, for instance, the Laplace operator, that combines multiresolution properties in both time and frequency domains.
Journal ArticleDOI
Stability of difference approximations of dissipative type for mixed initial-boundary value problems. I
TL;DR: In this paper, the authors use the results in matrix theory and Wiener-Hopf factorization to replace this restrictive assumption by certain reasonable assumptions on accuracy of W(t) and smoothness of an associated positive-definite symmetric matrix.
Proceedings ArticleDOI
A split Bregman method for non-negative sparsity penalized least squares with applications to hyperspectral demixing
TL;DR: An alternating direction (aka split Bregman) method for solving problems of the form min u ∥Au − f∥2 + η∥u∥1 such that u ≥ 0, which works especially well for solving large numbers of small to medium overdetermined problems.
Journal ArticleDOI
A multiple level set method for modeling grain boundary evolution of polycrystalline materials
TL;DR: In this article, Chen et al. employed a multiple level set method with a predictor-multicorrectors approach to reduce the gaps in the triple junctions down to the grid resolution level.
Global Minimizers of The Active Contour/Snake Model
TL;DR: In this article, LTS2 and LTS5 Reference EPFL-CONF-87269 Record created on 2006-06-14, modified on 2017-05-10
