An inertial forward-backward algorithm for monotone inclusions
Dirk A. Lorenz,Thomas Pock +1 more
TL;DR: In this paper, an inertial forward backward splitting algorithm is proposed to compute a zero of the sum of two monotone operators, with one of the two operators being co-coercive.

Journal ArticleDOI
Linear Convergence of Iterative Soft-Thresholding
Kristian Bredies,Dirk A. Lorenz +1 more
TL;DR: In this article, a unified approach to iterative soft thresholding algorithms for the solution of linear operator equations in infinite dimensional Hilbert spaces is presented, and a new convergence analysis is presented.
Journal ArticleDOI
Linear convergence of iterative soft-thresholding
Kristian Bredies,Dirk A. Lorenz +1 more
TL;DR: A unified approach to iterative soft-thresholding algorithms for the solution of linear operator equations in infinite dimensional Hilbert spaces is presented and it is shown that the constants can be calculated explicitly in special cases.
Journal ArticleDOI
Inline hologram reconstruction with sparsity constraints.
TL;DR: This Letter suggests the use of a sparsity-promoting prior, verified in many inline holography applications, and presents a simple iterative algorithm for 3D object reconstruction under sparsity and positivity constraints.
