Alternating Minimization Algorithms for Transmission Tomography

IEEE Transactions on Medical Imaging, 2007
A family of alternating minimization algorithms for finding maximum-likelihood estimates of attenuation functions in transmission X-ray tomography is described. The model from which the algorithms are derived includes polyenergetic photon spectra, background events, and nonideal point spread functions.

An Alternating Minimization Algorithm for Binary Image Restoration

IEEE Transactions on Image Processing, 2012
The problem we will consider in this paper is binary image restoration. It is, in essence, difficult to solve because of the combinatorial nature of the problem. To overcome this difficulty, we propose a new minimization model by making use of a new variable to enforce the image to be binary.

Metalearning-Based Alternating Minimization Algorithm for Nonconvex Optimization [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2023
In this article, we propose a novel solution for nonconvex problems of multiple variables, especially for those typically solved by an alternating minimization (AM) strategy that splits the original optimization problem into a set of subproblems ...
